It's a really common thing when you're gay, especially in small countries and cities, to deal with literally every gay knowing each other. For example, here in Greece, every gay has the other on facebook and you end up having like 300 mutual friends with people.
The question is, does finding out that your gay friends have been with a guy you like at the moment make you uncomfortable? Every time I discuss this thing with someone they always tell i'm "shaming" tbh but I don't see it that way.
For me, there is literally something very unsettling knowing that some close friends of yours have f***ed someone you like. It isn’t wrong, it’s a real thing that’s happening in the gay community and it doesn’t mean it can’t make people feel uncomfortable. I'm not sex shaming. If you had a connection with someone that isn’t based solely on sexual intercouse, you will understand.
