It's not impossible at all ! But i understand that person, as a gay men, playing as a female MC makes me uncomfortable because i like to self-insert myself in the game and there's nothing wrong with that, and nothing's wrong with asking the author if there's a option to add others gender's, and if they don't want to add, that's ok! the issue would be to curse the author or try to "force" them for not wanting to add that option!
i'm really sorry if im assuming wrong, but based on your name i guess you would be a woman? if so, it makes easier in your case cause that's would be your gender and it would make more sense to you and more easier to enjoy, i guess?
i mean, there's some awesome otome games out here with amazing romance options but in the end the MC is a woman and people treat her as a woman and with that some people can't self insert themselves in the game and can't enjoy, but i understand that not every game is cather to all audiences haha!
sorry for the long ass reply and sorry if i was rude! <3
