I'm 26 years old and haven't had a lot of serious girlfriends but I've noticed an upsetting pattern. I've only had 3 sex partners but all of them have at one point or another during intimacy called me the name of one of their ex lovers. For example, when we're having sex, the girl has said "I love you, (ex lover's name)". Two of these were serious girlfriends and each sex partner has called me at least one other person's name. Is this normal? How often does it happen to you? Does/would it make you upset? If so, how upset? I'm asking because I've never done this to anybody. Have you ever done this to someone and if so, how did they react? It hurts each time it happens but they always tell me it's normal and that everybody does it. Then, I ask them if they'd be hurt if I had done the same thing. In fact, I'm pretty sure they would've been pretty upset. Would you leave someone over it? It makes me sad because it basically tells me that they're fantasizing about some other guy they'd rather be with while they're sleeping with me. Once, I didn't call a girl out on it and she didn't even notice that she had done it.
