I don't self-insert and I'm into corruption of female characters. Female-MC gives the character in question more screentime and you don't have to interact with her through some annoying male MC.
People ask me that sometimes, even in games that aren't NSFW. For me personally I guess most games are what? 40 hours average? So if you ask me if I want to stare at a curvy apple female bum or a he-man extra male one, I'd rather the former.
i don't self-project into reader inserts, I'm not looking for emotional fulfillment from these games.
i play some games for entertainment others for how spicy and depraved the scenes are, male/female/futa mc doesn't matter
