The idea is that the "players consciousness" is transferred into a avatar-body at the start of the game. That body starts virgin to everything, so even if you love to drink "pee" for example, the first time the taste of the pee strikes the tongue of your avatar, will make the body feel disgusted. Regardless of your kink.

No,
In FemU-1, you can play as a dominant female, where you need to rape enemies to absorb their power and abilites and get stronger.
However, for having sex you need to restrain the enemy without killing them, ( which is way harder then simply reducing their hp to 0)
You can also catch some enemies and enslave them to farm their powers regularly.
Once you catch one enemy, you can also "train" them (which means torture them). This increases their abilites, their submissiveness and breaks their will.
But you have to be careful. If you overdo the torture, they might faint and be unconscious for a few days.
But honestly...
^ I wonder if you guys would even play this.
