There are videos from many sites that are not specified in the "not allowed" page (https://www.gaytorrent.ru/notallowed.php) that always get removed. Off the top of my head there's: Fraternity X; Treasure Island Media; Maverick Men; Sketchy Sex; The Guy Site…

Every time a scene from one of these sites gets uploaded it is taken down, does anyone know why? And is there a definitive list somewhere of exactly which sites are not allowed? I don't wanna unknowingly upload content that isn't allowed.

Gay themed? As is porn? or romance? Or just games with gay characters and scenarios?
Coming Out On Top by Obscurasoft comes to mind. It's a dating sim (sexually explicit)
There's also See No Evil by Bigfingers, which is an adventure game (sexually explicit)

Other than that, any Bioware RPG made in the last ten years allows for gay romance.
There's also apparently a gay subplot in "The Technomancer" which is a new Action-RPG, thought I haven't played that one yet so I can't tell you anything about it.
