This mechanic is to increase the efficiency that MC has with the female NPCs, but it doesn't work with the princess, she can forget Yarizo (Yarizo is superhuman in the sexual aspect). The only thing that I have seen that you can increase the love of the princess and take care of her mental state about the violations that she has on the enemies. eg: if she was raped, the love drops, and there is a plus that lowers the statistics if she has orgasms. But that mechanic is not optimized. It would be nice if Techno could open a record that we are free to modify in order to help as a community of modders.
