I said the males weren't you, not that they were.
Nobody "truly believes" they are literally a character in a game. You know, "discerning fantasy from reality." The vast majority of games on this site are written with a self insert and/or roleplay in mind. It's a simple and easy literary tool that serves as a vehicle for the player to perform actions they think they (the mc) would do (self insert), or think the character (author's protag name) would do (roleplay) to experience the story. It's all about immersion, and makes forming connections with characters you like fun if you're personally invested. I'm well aware not everyone self inserts or roleplays.
Which is why it makes even less sense, especially in your case, to want the MC to be female, since you're just about the spectacle porn anyway. You should have no issue if the MC is male or female, since either the male MC is going to corrupt a girl, or the female MC is going to get corrupted. Simple, no? Either way, a chick gets corrupted and fucked in some sort of way of your choosing, and that's really all you're interested in. In the case of this game, Femshep is already in the game. So why the fuck do you guys care whether she's the MC or some random guy is the MC if you want her to get nailed by some guy anyway? Both scenarios end in the same outcome. Seems to me the MC's gender is more important to people who roleplay/self insert and should be far less important to people like you.
