Okay, so let's say you've been dating your boyfriend for a while, and then he decides to tell you he used to have gay sex with one of his friends. It wasn't a emotional relationship, just a friend with benefits situation. How would you react if, up until this point, he made it seem like he was 100% straight?
I meant to say this was before he got into a serious relationship with you, sorry for not specifying that.
I'd be pissed he was banging someone else but I'd probably forgive him. I'd ask why he was turning to someone else for his sexual needs though regardless of gender. I might wonder if he was just gay instead of bi
We'd definitely be sitting for for some coffee and a talk ;)
