It's a good thing that disclaimer is there, else I'd probably have created an elaborate system where I drug people and lead them to a gloryhole so their semen can be harvested and fed into a machine that converts it into energy. Phew.
But in all seriousness, yeah the setup is strange. I don't think it's a case of mental illness, just a case of the creator having very specific ideas of what they want in the game (gloryhole-centric corruption with a reluctant MC), and doing all sorts of gymnastics to make it work in a coherent story.
