Away until August 2
Replies and updates are paused until August 2 while I travel and do exams. The mod is not abandoned and I am still reading the thread. If you are reporting a bug, post your log and your mod list with it. Without both I cannot act on the report when I get back, and I will only have to ask you for them then. A HugsLib log share link is ideal if you have it.
RJW Dynamics
A chastity ideoligion, a top/bottom dynamics system, anatomy reclassification, strap-ons, and male pregnancy for RimJobWorld.
RJW Dynamics replaces RJW's fixed gender roles. Traps and futas are reclassified so vaginaless futas can exist, caged subs become bottoms, and dominant pawns form lasting dom/sub bonds, and there are functional strapons. Nearly everything toggles in mod options.
Chastity ideoligion
A flat chastity cage, independent of RJW Extension, force-equipped on the submissive gender of an ideoligion with the Sexual Dynamics meme and cage precept. The cage shrinks the wearer over time and raises vulnerability; pull it off and size restores. Wearable keys open it through a targeted ability. The Sexual Dynamics meme drives a dom to hunt down their sub's key and demand it from whoever holds it. Keyholders clamor over a caged sub for a group mood boost, and a humiliation rite parades a naked victim while spectators jeer. Cages fit any body, male or female.
Top / bottom dynamics
Traits and penis size decide who tops, replacing RJW's gender rule. When sex starts the pair contests for the roles and it plays out in the social log: a decisive win, a close call, or a sore loser. Winners and losers form lasting dom/sub bonds from the contest alone, with no cage or chastity setup involved, escalating from equals up through enslavement, and transferable when a rival out-beds the current dom. Caged subs become bottoms over time and eventually lose the urge, and the ability, to top. A dom conditions their sub toward a chosen fixation, and the sub can inherit it. A strapon lets females top: a functional infertile penis that enters the contest.
Classification and pawn generation
Trap anatomy reads as futa everywhere RJW decides gender, so futas exist with or without a vagina. Real traps split into femboys and busty boys through a trap pill. The bio line shows what a pawn actually is, Futa or Trans, instead of RJW's Herm. Cage factions roll only the right genders at start, and the vagina split is configurable.
Male and futa pregnancy
An implant lets any pawn get pregnant, and anything with a fertile penis can do the impregnating: men, futas, femboys. So male/male, futa/male, and futa/futa all work. Biotech belly visuals, trimesters, and lactation when present, RJW's pregnancy as fallback. The social tab lists the carrier as mother, the sire as father. The baby's gender is fixed to one of the parents'. Works with RJW Genes. The implant is made at the drug lab or bought from a trader, so it does not need a high tech colony, and a fertility rite tied to the meme is a no-item alternative.
Settings: futa bias, trap replacement, gender labels, the top/bottom contest, dom/sub formation, fixation conditioning, fertility, pregnancy, and every caging feature toggle in mod options.
Requirements
Required: Ideology DLC, Harmony, RimJobWorld.
Strongly recommended: Sized Apparel Zero (SA0). Without it the cage, strapon, and genital visuals still render but sit at a fixed crotch position instead of tracking real size and body type, and the strapon won't animate during sex. All mechanics work either way.
Recommended: Biotech DLC for full male-pregnancy visuals and lactation.
Optional: RJW Extension, RJW Sexperience, RJW Genes, Underwear (s16 / UnderWhere), Cumpilation.
Install
Unpack into RimWorld\Mods (the folder should read RimWorld\Mods\rjw-dynamics). The compiled DLL is committed, so a fresh clone is playable with no build step. Also works with git mod loaders (e.g. Libidinous Loader): add a custom git provider pointing at the repo URL below, branch master.
Load order: Harmony, then Core, then your DLCs (Biotech included), then RimJobWorld, then Sized Apparel Zero, then RJW Dynamics. Put any other RJW add-ons before RJW Dynamics so its patches apply last.
Caveats: Adding to an existing save is fine; removing mid-save is untested. Wrong load order usually shows up as missing textures or red errors on load. If the mod list resets to just Core and the DLCs on the next launch, one mod in the chain failed to load (almost always a missing dependency, not RJW Dynamics); read the log before reordering anything.
Compatibility
Incompatible: RimNudeWorld (it duplicates and fights SA0). Plus several pawn-generator-hijacking mods; the full list is in About.xml. Built and tested on RimWorld 1.6.
FAQ
What does this mod actually do?
Short version: it fires RJW's fixed gender rules and makes who-tops-whom something pawns fight over instead. Traps and futas get reclassified so vaginas on futas are optional and RJW's "traps" (males with breasts) are replaced with femboys. Chastity, dom/sub bonds, and kink conditioning are earned through play rather than flipped on, and any pawn can carry a pregnancy with an implant. Almost everything worth touching has a switch in mod options.
Can I add this to an existing save?
Yes. It is safe to add mid-game to a save that never had it. Nothing is rewritten on load; existing pawns are untouched until you act on them. Removing mid-save is untested.
Is Sized Apparel Zero required?
No, but strongly recommended. Without it the cage, strapon, and genital visuals sit at a fixed crotch position instead of tracking real size and body type, and the strapon won't animate during sex. All mechanics work either way.
Is RJW Genes compatible?
Yes. The RJW-Genes femboy gene is reshaped into this mod's flat femboy. The gene only activates on male carriers, so a female who carries it stays a plain female and passes it on. A mod option turns that off and makes every carrier a femboy. Male pregnancy runs on its own implant path, so the two do not conflict.
What is the difference between a femboy and a trap?
Almost none; both are male. The difference is in look and a tweak to orientation that makes femboys primarily gay and bisexual, straight femboys do exist though. RJW's old "trap" is a man with breasts, and this mod turns those spawns into femboys instead. By default, every trap becomes a femboy, so in practice they are the same thing. The man-with-breasts version only survives through surgery or if you lower the "Femboy share of trap spawns" slider.
How do I get femboys and trans pawns but not futas or old-style traps?
Turn on RJW's own futa/trap generation with a spawn percentage, then turn on "Futa-fy traps". Set "Vagina-less futa chance" to 100 for trans, and "Femboy share of trap spawns" to 100 for femboys. To skip RJW's trap option entirely, leave it off and use "Femboy spawn chance (RJW traps off)" instead.
The trap pill only shows Male or Futa in the bio, never Trans.
"Trans" is the label for a futa with no vagina. Two mod options gate it: "Show RJW gender in pawn bio" puts the RJW classification on the bio line at all, and "Label vaginaless futas as Trans" makes that class read Trans instead of Futa. Both have to be on. Since your bio already shows Futa, gender-in-bio is on, so flip the Trans-label option. If you scroll up from this FAQ, you will see the picture in the "Classification and pawn generation" section that shows the exact surgery flow. The trap pill turns male pawns into femboys AND makes males with breasts turn trans. Femboys surgically given breasts also become trans. What isn't expressed in the screenshot is that this process is completely reverse-able. Trans pawns given male nipples become femboys, femboys that take the trap pill flip to normal males.
Can males get other males pregnant?
Yes. Any pawn with a pregnancy implant can get pregnant, and anything with a fertile penis can impregnate: men, futas, femboys. The baby's gender is fixed to one of the parents', so male plus male is always a male baby.
I installed the implant but males never get pregnant.
Pregnancy only triggers when the implanted pawn bottoms during anal sex. If he keeps topping (high dominance, a hulk body, a tough trait) he won't get pregnant. Turn on "Implant carriers prefer to bottom" and he will lean toward bottoming.
Where do I make everything?
Chastity cages at a smithy. Trap pill and pregnancy implant at a drug lab (the implant is also sold by traders). Strapons at a tailoring bench. A fertility rite tied to the Sexual Dynamics meme is a no-item pregnancy alternative.
Does this work on a tribal or medieval colony?
Mostly. Cages need a smithy and the trap pill needs a drug lab. Only the pregnancy implant wants a drug lab or a trader, and even that can be skipped with the fertility rite.
The strapon renders in the wrong place, like up at the neck.
The strapon is placed to sit at the crotch with or without Sized Apparel Zero, so a strapon up at the neck means one of this mod's patches broke or got overwritten by another mod. Report it with your log and mod list. The "Strapon height offset" slider can nudge the shaft for fine-tuning, but it is a band-aid, not the fix for neck placement.
How do quirk fixations work?
A dom's act-quirk sets what they train their held subs to crave, shown on the Dynamics tab. With the quirk-driven scene option on it steers scenes, and with fixation propagation on a sub eventually learns the quirk for good. It pulls quirks from RJW's quirk system, so a quirk mod like RJW Additions gives it the most to work with.
How do I build my own cage ideoligion?
The Sexual Dynamics meme is the base and a set of precepts determine what gender doms, what genders subs, if doms have a certain quirk, and if cages are required. Supremacy memes are compatible but they force the precept for the ruling dom gender.
Something broke.
Most things gate on a mod-options toggle. Turn the offending feature off and report it in the thread with your log and mod list.

What's New in Version 1.1.3
Released
- The sadist's cage now reads from its own texture folder. Re-texture mods can reskin it without changing the tiny cage.
- Cage art is now preloaded for every cage, not only the standard one. A cage added or reskinned by another mod no longer risks drawing blank.
- Leaving version 1.1.2 up in case something breaks.
