Short answer is that it will be there, but isn't at the moment. The game's setup is similar to darkest dungeon, but instead of stress, its lust. So as your characters progress further in the dungeons, and get more exposed to various lewd things, they get more and more lewd and corrupted. Then its up to you how you want to manage their lust/corruption.
I, (to my peril probably) takes a traditional approach to game dev. I like to lay strong foundations first, then build on top of it. I don't really consider what's available even alpha 0.1 worthy - its still missing many core features, but I'm getting there. And TBH I rather make the title debut much later, but it can't be helped, I guess.
