Nope, no kinks whatsoever, we're both just really sexual and aren't afraid of trying things. What really put me off were stories from the friend such as: "So there was this one girl that we both had sex with during the same time period, at first I would have sex with her, then he (BF) would have sex with her, and we had that kind of friends-with-benefits sharing party for a couple of months." or something in the lines of "This one night he's having sex and I'm having sex as well in the other room and we're trying to be as loud as possible in order to compete.". I really didn't want to hear this, or at least it could have been funny if my boyfriend told me these things, but he was there during that storytelling session, and he was visibly uncomfortable. Later on when we were alone he was pretty quiet but made sure I know that if I have questions that he would answer truthfully. I just asked about STD's and whether or not he is into that stuff still and for both he said no. I felt insecure for a moment, sure, but I really don't want to judge him for his past, and I'm not going to. I'm just trying to figure out the situation with a clear head.
