Fortunately that's very limited. There are two characters that might be considered male with whom the MC has an affair, but they're not really men.
This is not that kind of game. Most of these aren't.

Oh? You WANT gay sex?
Uhhhh... yes, that might be a problem indeed. There are several she-male games, but I don't know much about those. Not my cup of tea.
I'm 0% homophobe, so I hope you find something to your liking, but I'm also hetero, so for me, it's not at all alluring. So I can't help you, unfortunately.
I mean, they said "I find these aliens to be really hot, mainly Doarn." and you STILL did not understand that they WANTED gay sex? 😅
I guess this is to be expected from someone who does not even realize that such a claim as "I'm 0% homophobe" is so exaggerated that it feels fake, especially after your first reaction when you thought he shared your homophobia and you answered "Fortunately that's very limited.", it's too late to pretend now since you grilled yourself from the start. 😉
I got one for you.

It's more comedic than Tales, but it has gay, straight, and in between options.
