Nah, MC wants to adventure so badly, the sex is just a method for him to level up so he can go deeper into the dungeon to explore. It's the same cycle again and again.
I'm waiting for either of two things: him realizing that the dungeon's warping his mind just as much as he's warping the girls' minds (almost got a hint of that in this chapter), or him getting bad end'd for being such a piece of shit.
