I'm a guy and I just don't have this fetish of being fuck by guys even on a game, but I maybe can tolerate being fuck by the son and lesbian.
You can play female MC games from a more top-down perspective. Like god leading the protagonist into situations and identify in H-scenes as the current guy fucking the MC (in different situations).
If "If you play as a girl the player must crave for dick in real life too" is your first (and only) association... may be a Freudian slip!?^^
The "maybe i can tolerate beeing fucked by the son" makes it even better, like "I would never fuck a dude... im a guy! But if i had to..like...i would totally choose my bro. Hes so handsome...with those muscles...and his big D...*rawr*.......but im not gay....just thinking about it....daily..... ( ' - ') " XD
conclusion: Female MC games may not be for everyone, but there is more than one perspective and u can enjoy them as a guy, without liking dicks...
