The attractiveness is based on the current appearance of the sim. This applies to occult/human forms but also to the different outfits (even for humans). Let's say your alien has blue eyes on his human form and red eyes in his alien form. If a sim who likes blue eyes and dislikes red eyes sees him while in his human form his eyes will add to his attractiveness, but if the same sim sees him in his alien form the red eyes will make him loose attractiveness points. As for CC, it can work with the attractiveness system, but only if it's properly tagged. If the eyes look blue but they are tagged as yellow, the attractiveness system will treat them as yellow and vice versa. If you want to make sure that it works, you'll have to open it with sims4studio and apply the proper tags if the creator hasn't done it.

To be fair it's quite hidden haha I only found it because it was linked in the last changelog and I always read them before installing a new WW version... It should be added to the op additional mods list

It already exists

Not just you, I've got the same issue. Today I've noticed while playing with a married couple that with the current version the only moodlet they get is "Quikie with a hottie". With the older version I only got that one with single sims, while married sims got one of the different moodlets for couples. The problem is still there after removing every other mod, cleaning the cache and starting a new save so... it could be a bug

Use the body selector to choose the sim's erect penis. If you used the body selector but only chose the flacid penis or you equiped it in CAS it won't work during sex

If you enable offline mode it won't download updates unless you disable it again. The only problem is that it won't let you access the gallery, it's like playing without internet

Batuu aliens are NPCs, just like the easter bunny, Patchy or The Grim Reaper. Those of us who use adult mods sometimes forget about the fact that the vanilla game is only 12+ rated... Why would they spend time and resources into making nudeable NPCs that aren't supposed to get naked ever? The only way I can think to make it possible is installing cc that adds the alien heads as skin details, hats or something like that and then use MCC like @babuchassaid or find a mod that replaces them. I found this one with a quick google search https://twitter.com/NeilSimming/status/1303733634185207809, but there could be others. I don't own that pack, so I can't test it and I don't know exactly if it's just a skin detail that you have to apply manually or a default replacement, but you could give it a try

Yes, but you can still use a computer to access the online store and they will deliver it to your mail

They don't arrive inmediately, you have to wait (I think it was 1 sim day, but I'm not sure). After that, they should be in your mailbox if you have one and the delivery person can reach it. Or if you don't want to wait you can buy everything directly in buy mode. Use the search box if you can't find something, type Kaya for period related products and Wicked for everything else.

Tienes una versión del juego muy vieja. Mira en el primer post qué versiones son compatibles y actualiza a alguna de esas

@onesumgame Uploading here a file that you know causes issues with WW isn't probably the best idea... Some people download everything they see without reading what it is and what it does. It's better to simply write the name of the problematic file, just in case

Some other mod or cc that you have must be overrinding the default bodies, downloading more things won't solve it. Use the 50/50 method on your mods folder until you find what's doing that

By partner I didn't mean other sim in the household, I meant the sex partner. You have "NPC Sims Birth Control Use Behavior: Moderate Mode" setting on, that means some NPCs will own and use birth control. So if your sim has sex with a NPC that has condoms in their inventory, your sim will use them. It could be a bug, yes. But there's that possibility too

Sims can use condoms from their partners' inventories too if they have some

Not that specifically, but you can shift-click on the sim -> Wicked -> Sex -> Disable undressing in sex. That way that sim will keep what they're wearing on and then you can undress them manually during sex and choose what you want to remove. There used to be another way using MCC to edit the bath outfit of that sim, which is the hidden outfit they use when they shower/bath, then go to WW settings -> Nudity settings -> Outfit undressing settings -> Advanced outfit settings -> Complete undressing type -> default, though I don't know if this is still working. Another workaround would be to change the cathegory of the hat to skin detail with sims4studio, that way it will stay always on no matter what the sim is doing or which outfit they are wearing (or not wearing hehe).
