So my bf of 9 months keeps asking me to have a 3 some with him even though I tell him how uncomfortable I am with the whole situation (however I'm bisexual, we've done something like that but I just ate some girl out and my bf never fucked her) I told him I don't want to have one and he keeps pushing.. keeps saying it's not fair that I didn't let him fuck some girl too.. but I regret it and tell him.. I'm at the point where when he brings it up I cry and just tell him fine if it makes him happy then he gets mad.. he says he loves just fucking me but he wants to do things with me and that he's not a "boring person" what should I do? Should I force myself to have a 3 some..??
