It have nothing to do with homophobia. You want to fuck (or be fucked by, idunno) a guy – you need a game that have respective premise.
You don't go to homosexual game and ask for hetero sex. You don't go to Hardcore BDSM section and ask for vanilla missionary. You don't go to MILF category to ask for college girls. You don't go for JAV for Blacked Latinas. Leaving porn, you don't go on Disney movie for gore, you don't play Starcraft to get FPS experience and you don't buy yourself a beef stake when you're vegan.
It would be reasonable to "add more gay scenes", if it already was bisexual, but hetero wouldn't want or need homo POV.
Lack of western "Gay Men" would be it's own problem and in no way a reason to shove theme where they're out of place. It's porn. There's a reason why those things are separated everywhere except trash places.
