Popular Post asdt123123 Posted December 31, 2025 Popular Post Posted December 31, 2025 Procedural Penis Animations/Collision [Beta] View File Physics mod that procedurally animates/aligns the penis, and adds visual collision to the anus and vagina (Like CBPC does). It's designed to work perfectly with CBPC - actually I didn't test without CBPC even.. The penis will now properly be pushed into either the mouth, vagina, or if the scene is tagged as "anal" the anus. It will then follow the vaginal canal, anal canal, or throat. Meaning that if an animation is offset, the penis will still find it's home! However, if the animation is super offset, obviously don't expect a miracle. Make sure you mess with the /skse/plugins/accurate-penetration.toml- plenty of features are disabled by default and you may want to better correct hole/canal positions! Please read the config section before commenting. 95% chance your question/concern/complaint has already been solved Not working? Your Sex mod (OStim, Sexlab) is outdated. This ONLY works with OStim-Standalone v7.3.5a+ and newer Sexlab/P+ versions. Fully updated? Check for mod conflicts with your sex mod Also check %USERPROFILE%\Documents\My Games\Skyrim Special Edition\SKSE\AccuratePenetration.log Original Position VS PPA animating: Requirements: Address Library Crash Logger: Not required, but just get it. It's amazing SKSE Menu Framework: Optional unless you want a mod menu and some other minor UI elements Skyrin SE or AE. Sexlab or Sexlab P+ or OStim Standalone (Latest version for all of these ONLY. OStim will NOT WORK if it's not v7.3.5a+) A modern Skyrim body like 3BA, or UBE with anus/vagina bones that aren't shit Slightly incompatible mods UBE Penis: Bones are offset. You must go into bodyslide and move the penis mesh UP using the Penis->Height slider to fix it. TRX Male Penis: Penis tip can't bend. You must go into bodyslide and try and shrink the end portion of the penis more. It works fine, but just wont look as good as VectorPlexus's penises Mu Joint Fix: Causes sex animations to get offset. Works, but if you notice stuff getting offset - that's why. Features: The penis will now be fully procedurally animated and properly enter and follow another actors orifices/mouth during sexlab scenes Anus, Vagina, and Mouth penetration are all procedurally animated Handjobs are procedurally animated Like CBPC, the anus and vaginal will now have penetration physics. However - unlike CBPC, penetration is highly accurate Option to disable animations gaping the anus Highly customizable blowjob animation expressions. You can easily simulate deep throat expressions. By default it'll just insure your character's mouth is open during blowjob scenes (Common Sexlab bug fix) Properly aligns the penis with the orifice/mouth/hand it's going to penetrate. Toggle the mod on/off by opening the console (~) and pressing F2 Dynamically change an actor's penis target. Swap between the vagina and anus on the fly UI menu option to fix an actor's face when facial expressions get bugged by a mod Ability to create custom, advanced facial expressions that override Sexlab/OStim's during scenes (Optional) Dynamic expression preset system based on penis/sex variables (Optional) feature to force the penis to use a futanari character's anus instead of vagina (Optional) Procedural Sex Sounds. Very realistic sex sounds will play during all animations Highly configurable in accurate-penetration.toml (Review the config, lots of cool features are disabled by default!) Controls & Hotkeys 'BACKSPACE' by default while aiming at a scene participant will open a menu and allow you to set their schlong target. This is PER STAGE, so the next stage will go back to default. However you can press "Save" to permanently save your changes! To clear your changes, just press the reload config key (Possibly a few times, it's re-loaded async). Called "SelectActorKey" in the config 'F5' by default will RELOAD your /skse/plugins/accurate-penetration.toml config. "ReloadKey" in the config 'F2" by default will TOGGLE this mod on/off. "PauseKey" in the config But I want SMP/CBPC genital collision handling! Open the /skse/plugins/accurate-penetration.json config, disable "HandleOpeningPhysics". Procedural Sex Sounds This mod has an optional built-in procedural sex sound module that'll simulate realistic sex sounds during animations. It's EXTREMELY easy to configure, add/remove files without dealing with esp files, and IMO sounds better than any other solution out there. It only provides sound effects for vaginal, anal, handjobs, and blowjobs - as it's purely intended to be an addon to the functionality already provided by this mod. Do not expect kissing sounds.

So if you can't get this mod working well (Constantly offset at certain angles) - that's why. You should check out the penis in Nikskope. It might be fixable in bodyslide if there's any sliders that allow shifting the entire penis up. If your body doesn't contain the bones this mod expects, you'll need to find them and put them in the /skse/plugins/accurate-penetration.toml config. Penis morphs that don't physically move the bones too wont look perfect. Gangbang participants may use the wrong holes at times, use the '0' menu to change their target Known issues & How to Solve Them If an animation mod (Like Billy's animations) open the anus/etc - it will basically double the anus opening size. Solution: Use the modified skeleton provided by this mod If an animation has an actor rubbing their cock on the vagina/anus, it's going to penetrate. No rubbing allowed with this mod! Solution: Temporarily pause this mod with F2, or select the actors true intent in the action menu (Backspace by default) The holes are offset, or you dislike the organ animation Solution: Open the /skse/plugins/accurate-penetration.toml config and mess with the offsets (Read configuration below for help) You don't want this mod controlling anus/vag opening Solution: Again, open the accurate-penetration.json config and disable "HandleOpeningPhysics" Some penis rigs - have strange bone vertex weight painting. This means if PPA (This mod) moves the penis to a position, the mesh will actually lag behind a bit for certain bones. Which will make certain animations look slightly offset. Solution: edit the mesh, and re-paint the bone vertex's in Outfit Studio. Softbody has issues with this mod Solution: Softbody has a patch on their Nexus page for this mod. You must also change "HookPosition": to 2 in the /skse/plugins/accurate-penetration.toml config. The penis goes in the wrong hole or doesn't go in any hole. Solution: Some animations are verry offset, you'll need to increase "PenisActivationRange" in the /skse/plugins/accurate-penetration.toml config. The anus or vagina don't open, or open weirdly! Solution: Use the modified skeleton provided by this mod UBE penis doesn't work well Solution: This is due to the penis being "below" the skeleton. You must MOVE IT UP in body slide using the "Height" slider in bodyslide. The penis flickers in-and-out of the hole. Solution: Some animations are verry offset, you'll need to increase "PenisActivationRange" in the /skse/plugins/accurate-penetration.toml config. You can also just manually bend the penis in the correct direction Male character penises don't activate during masturbation Solution: Turn "ignoredMaleActors" to false in the /skse/plugins/accurate-penetration.toml config Planned features: Better gangbang support - Control it with the 'BACKSPACE' menu or make a custom animation tag file Potentially near-skinning of penises, so giant penises vs small penises will act differently. Added in 0.0.24 Sound effects module - Added in 0.0.22 Dynamic facial expressions module Added in 0.0.24 Handjob support - Added in 0.0.19 Reporting bugs: Crashed? Use Crash Logger SSE. Have weird animations? Show a video, gif, maybe a screenshot will suffice. Penis not lining up? Tell me your body type, and show some screenshots and what not. Also make sure you verify it happens with every animation. ALL bug reports must contain %USERPROFILE%\Documents\My Games\Skyrim Special Edition\SKSE\AccuratePenetration.log and your screenshots MUST contain ALL the relevant visual debugging or you WILL BE IGNORED Configuration You can find your config file in Data\SKSE\Plugins\accurate-penetration.toml You can RELOAD this config in-game by opening the console (~) and pressing F5 Here's a tutorial on how to properly change the offset positions of the anus/vagina and what not: Spoiler For simple editing, you can just use the in-game editor! I only recommend this tutorial for finding different bones to attach nodes to, if you only want to EDIT the hole position slightly use: Backspace (Opens action menu) -> Edit Hole Positions -> Whatever Manual tutorial: To change a hole position on a body, you need to adjust the offsets in the config. We'll be using Nifscope to find our offsets, since it's easier. You can specify a spline of "DepthWaypoints", or you can specify a single "DepthOffset". You can't do both - so pick one or the other. You want a simple tunnel (DepthOffset), or a more elaborate tube for the penis to follow (DepthWaypoints)? Tips: - The pelvis is the most stable bone to use. Others are skinned, and may shift around in-game - I recommend you keep the "tunnels" - or in other words, DepthOffset - away from each-other. Like you don't want to cross the anus and the vagina nodes since other physics mods will pick that up and assume double penetration. Unless you're using all of this mods features! - You should keep the collision cylinder as a perfect shape of the anus/vagina tunnel. No sense in making it larger then it needs to be since we already force the penis to penetrate properly. This tutorial assumes you're just specifying a simple DepthOffset. The procedure for DepthWaypoints is virtually the same though, just obviously more points to draw a shape rather than a straight line. Nifskope: 1) Load up your body, usually named Femalebody_1.nif or something. Then expand the first NiNode (Usually named Scene Root). 2) Now scroll down and find a good bone to use. Pelvis is my favorite because it's solid. 3) Select that NiNode (Pelvis in my case) 4) Right click it, and select Node>Attach Node. 5) That'll open a small UI, select 'NiNode' from it. This is where we want our penis to ENTER/bend 6) Now you've got a fake bone to work off! We can now translate this NEW bone by selecting it 7) Then Right click, and go to Transform->Edit. 8 ) In this menu, you ONLY want to change the Translation: X,Y,Z. Move the fake bone to where you want the penis to enter. You should end up with something like this: 9) Now copy those translation coordinates, and put them in your config. Replacing the "Offset" coordinates. And press "Accept". 10) Now you need a DepthOffset. Click your new node, and once again attach an 'NiNode' to it. 11) Basically repeat those steps, and get your canal mapped out. Should look something like this: 12) Now take those new translation coordinates, and put them in the "DepthOffset" 13) Perfect, you're done. That was easy?

Spoiler Animation Action Tags Tutorial What Are Animation Action Tags? Animation Action Tags allow you to explicitly tell the mod where each actor's genitals should be targeting during specific animation stages. By default, the mod uses heuristic detection (guessing based on scene context and tags), but this isn't always accurate. Action tags give you precise control. When would you need this? The mod is targeting the wrong hole (e.g., vaginal when it should be anal) An actor's genitals are clipping through air or the wrong body part You want to disable tracking for a specific actor in a scene The automatic detection just isn't working for a particular animation Understanding the System Target Values Each actor position (1-5) can have one of these targets: V (Vagina) - Target the vagina A (Anus) - Target the anus M (Mouth) - Target the mouth H (Hand) - Reserved for future use (placeholder, does nothing currently) ! (None) - Disable tracking entirely. The actor's genitals won't be pushed toward any target. b (Auto) - Don't specify the key at all, and the system will figure it out using default heuristics (Doesn't work in manual mode). Actor Positions Actor positions (1-5) correspond to the order actors appear in the animation framework (SexLab, OStim, etc.). Position 1 is typically the "main" actor, position 2 is the first partner, and so on. Important: The target you set for an actor defines where their genitals go - not what happens to them. So if Actor 2 has target V, Actor 2's penis will target a vagina. JSON File Structure Animation tags are stored in JSON files within the mod's data folder. The mod loads all .json files and merges them together. File Priority (Important!) Files are loaded in reverse alphabetical order, with later-loaded files taking priority. This means: z_something.json - Loaded first (lowest priority) a_something.json - Loaded later (higher priority) 0_your_custom_tags.json - Loaded last (highest priority) Your custom tags should go in 0_your_custom_tags.json - this ensures they override any bundled defaults. 0_your_custom_tags.json is used by the in-game menu, so if you want to keep it separate then don't use that file. Basic Format { "AnimationName": [ { "s": 1, "1": "V", "2": "!" }, { "s": 2, "1": "V", "2": "!" }, { "s": 3, "1": "A", "2": "!" } ], "AnotherAnimation": [ { "s": 1, "2": "M" } ] } Breaking it down: "AnimationName" - The exact animation ID from your framework "s": 1 - Stage number "1": "V" - Actor position 1 targets Vagina "2": "!" - Actor position 2 has no target (disabled) Extended Format with Manual Flag { "AnimationName": { "manual": true, "stg": [ { "s": 1, "1": "V", "2": "!" }, { "s": 2, "1": "A", "2": "!" } ] } } The "manual": true flag tells the system this animation is fully manually tagged. When set: Any actor position not explicitly defined will default to None (disabled) instead of Auto Useful when you want complete control and don't want the system guessing Method 1: In-Game Editing (Recommended) The easiest way to tag animations is using the in-game menu during an active scene. Steps: Start an animation scene Open the target menu (check your keybinds - by default '0') Look at the actor you want to modify (crosshair targeting) Select the appropriate target (Vagina, Anus, Mouth, None, or Auto) Repeat for other actors/stages as needed Select "Save Changes" to write to your custom file Note: Changes are applied immediately for testing, but won't persist across game sessions until you save them. The save function writes to 0_your_custom_tags.json. Method 2: Manual JSON Editing For bulk edits or when you can't test in-game. Step 1: Find the Animation Name Enable debug logging in the mod settings. The log will show entries like: Status for ActorName: Context:[Anal] Stage:2 ... Or check your animation framework's documentation/tools for animation IDs. Step 2: Create/Edit Your Custom File Open 0_your_custom_tags.json in a text editor (create it if it doesn't exist). Step 3: Add Your Entries { "SexLabAnimation_Missionary_A1": [ { "s": 1, "1": "!", "2": "V" }, { "s": 2, "1": "!", "2": "V" }, { "s": 3, "1": "!", "2": "V" }, { "s": 4, "1": "!", "2": "V" }, { "s": 5, "1": "!", "2": "V" } ] } Recommended Mods UBE: Fantastic high poly body. I'll never go back to 3BA. Oh and it works great with this mod High Poly Head SMP: Adds SMP skinning to the mouth and throat. Looks great. Sexlab P+: Not without issues of it's own, but this mod will significantly speed up animations and has a hole new feature set. Why Does This Penis Look Worse Than This Penis? Basically: The vertex weights are not good for the bone's penis sections. Something you could solve in Outfit Studio. Here's a more detailed write-up of this problem: Upload Information/Schedule (For mod-list authors) Any file that contains "WIP" or "Alpha" is subject to removal once I exceed the uploaded file limit. These files, while all seemingly stable, are intended to be "developer snapshots" for those interested in helping me test and provide feedback for new builds. In other words, if I run out of upload slots and have to remove a file - an alpha version, even with a newer version, will be pruned over a build considered stable. If you want to insure your mod list file URL lasts long before going stale, I'd recommend choosing a non-alpha build.

Ondine. Posted December 31, 2025 Posted December 31, 2025 (edited) Mods made for UBE and Sexlab P+ out of the box, it is truly 2026 2025! to say the least, this feels like a nice plug-n-play alternative to what we have been dealing with so far. instant download Edited December 31, 2025 by Ondine. 1
Theess12 Posted December 31, 2025 Posted December 31, 2025 (edited) this is my most anticipated mod by far finely someone creates a plug and play solution for human dick alignment also big possibly dumb question does this work with TNG, clarifying that for the average Modder would be a huge help Edited December 31, 2025 by Theess12
necross 413 Posted December 31, 2025 Posted December 31, 2025 will this be compatible with Soft Body?
ebbluminous Posted December 31, 2025 Posted December 31, 2025 Nice to see the limits of Penis Science™ is still being pushed to the limits... 5
zioklone Posted December 31, 2025 Posted December 31, 2025 It seems to deliver better and more natural results than softbody. I hope you can improve the effect of 3BA, since it's still the mainstream option. As for P+, I haven't tried it because this mod has poor compatibility with other extensibility mods. I’d prefer testing on a more widely applicable version instead.

Man, I was laughing about the same thing. It's nuts that skyrim modding still reaches new peaks like this. Even jokes aside, this is some impressive physics simulation at this point. 2
asdt123123 Posted December 31, 2025 Author Posted December 31, 2025 Appreciate the testing guys. As for: Does it work for X? Idk, I don't really test the mod much so I'm hoping you guys can tell ME that lol. It should work for all standard schlongs though for males, otherwise those same schlongs wouldn't work for SOS/TNG. Body compatibility- I'm going to adopt a similar system to UBPC where you can bind points to bones/anchors. So you'll be able to easily adjust the offsets in-game. 2 hours ago, zioklone said: It seems to deliver better and more natural results than softbody.

I’d prefer testing on a more widely applicable version instead. Sexlab is easier to support than P+, so it most likely works. With Sexlab I can just read their papyrus variables, with P+ I have to literally find their C++ functions in memory. So in other words: Sexlab should work perfectly unless someone says otherwise. I would test with it, but it takes so long to start simple scenes I can't be bothered. 2
NCK30 Posted December 31, 2025 Posted December 31, 2025 (edited) For me the vagina is opening like mad. I am using BHUNP. But the penis is bending like it should. Though it seems to make it somewhat shorter. I also use these 2 mods. https://www.nexusmods.com/skyrimspecialedition/mods/82745 https://www.loverslab.com/files/file/22048-cbpc-separate-anal-collision-22-cbpc-156/ Edit.: Changing VaginaScale and BaseOrificeRadius seems to be the solution. Will test further. VaginaScale should be at 2.0 at most. BaseOrificeRadius is fine at standard 3.5. Edited December 31, 2025 by NCK30 3
NCK30 Posted December 31, 2025 Posted December 31, 2025 (edited) - The mod completely eliminates control of SOS adjustment. - Making Sexlab adjustments have no effect.. The penis stays the same place that it was. The Head is fixed in the same coordinate. - But it is bending, as it should. I just need to able to adjust bad allignment. - Penis seems to get crushed with some animations. Realistic enough I guess. But half the size that's too much. Edited December 31, 2025 by NCK30
NCK30 Posted December 31, 2025 Posted December 31, 2025 Adjusting with SAM (Screen Archer Menu) has no effect either.

NCK30 Posted December 31, 2025 Posted December 31, 2025 These settings. What do they do? "BaseOrificeRadius": 3.5, "PenetratorGirth": 2.5, "TipExtension": 5.5,
NCK30 Posted December 31, 2025 Posted December 31, 2025 Can I change the coordinates that the penis is locked to. Just needs to back it slightly and it fits perfect. I must say. This is a gamechanger. Mod of the year if the quirks can be solved.
NCK30 Posted December 31, 2025 Posted December 31, 2025 Pussy lips are completely static. Going to wait with this one until I gets further in development. For now it just Overwrites too much of those sweet collision effects.

BeefyJackal Posted December 31, 2025 Posted December 31, 2025 How difficult would it be to enable this in ostim scenes?
asdt123123 Posted December 31, 2025 Author Posted December 31, 2025 (edited) 11 minutes ago, BeefyJackal said: How difficult would it be to enable this in ostim scenes? Ehh right now it only uses Sexlab for finding actors involved in scenes, and the tags. Sooo should be easy? Do people use SexLab and Ostim on the same save or...? Only issue is I've never used it, so I would have to read their code line by line to figure out how to get the active scenes, tags, etc. Then I would have to spend more time testing it. So official statement is: Not planned for ALPHA releases, but it's something I can look into after this mod is stable. 3 hours ago, COLOCO said: Bhunp?! Next update you'll be able to configure the offsets and what not. So if some kind soul does that, and provides it here I can add it as an option. Edited December 31, 2025 by asdt123123 1
flatearthertom3 Posted December 31, 2025 Posted December 31, 2025 Tested it a bit: it works great for human males with sos when im in cbpc mode, but when i switch back to SMP smp collisions are dead even for creatures. Would be cool if this could be turned on and off in the future so it could be used alongside SMP as an option.
friendlygaint Posted December 31, 2025 Posted December 31, 2025 Can't test it atm but how does this work for male x male if the animation says vagina? (since i turn gender tags off) would it also support other mods like high poly head for male character? thanks
