Just click on a Sim and go into Wicked -> Personalization -> Role Assignment -> Gender Role and “Allow Any Gender Role”. It enables the Sim to play both the Male and the Female role in sex at the same time, which is especially useful for same-sex pairs, without altering all Sims behavior in the world via settings. You can find it under “Wicked -> Settings -> Sex Settings -> Dynamic Animations Disabler and Wicked -> Settings -> Sex Settings -> Autonomy Settings -> Dynamic Autonomy Animations Disabler”. You can select a sex category, orientation, number of participants, or location category and all animations that fit the criteria will be disabled.
