Well that was a dead end
I asked my boyfriend if he would consider having a relationship with the guy we've been talking to, and whom he wants to be his friend with benefits. His response? A resounding no. But, then here's the kicker. He wants the guy to be only with him sexually. I told him that he can't expect him to just fuck him and be happy, especially when he's bicurious. I told him he's gonna probably want to be with a girl at some point. To which my boyfriend replied that that's fine as long as we know who it is and that he gets tested. Ok, well that's fair enough I thought. But then he adds on that he definitely doesn't want me and the other guy to be together sexually. I wish I could open up his mind some more, but for the time being it seems to be completely closed shut.
