My boyfriend just told me that there's this guy that he has sex with to play out his fantasies. Of course I feel betrayed, but I don't want to overreact. He said he would stop, but I don't want to MAKE him do anything 'cause I don't want to hurt him. I just don't really know the best course of action. Advise please? (Please don't say anything mean. I love him to death, and I know he feels the same for me. This is just a little... roadblock that I need some help with)
