Yeah, got to make the MC realistic and properly squared away with all his flaws (half the love route literally focusing on him being a quick shot). You have to self insert of course...
But all the other guys female MC fucks? yeah, no, they're giga chads ripped out of fantasy. They can last forever, go multiple rounds and have massive dicks, all for the sake of realism of course.
Just abandon the love route since clearly even that is filled to the brim with trying to make the MC a pathetic cuck.
