My question is a little bit embarrassing but I'm going to ask it anyway because it's really been bothering me. I've been with my boyfriend for a bit over a year now, and he's my first real serious boyfriend. We are both 25 yrs old. My boyfriend recently revealed to me that every once in a while he thinks about when he would have sex with his previous girlfriend which turns him on. He's even masturbated to the thought of having sex with her. Both intercourse and oral. I'm embarrassed to ask this question. I'm wondering if this is an indication that there is something wrong in our relationship. He states that everything is great and we don't have any problems in bed. It's just been bothering me since he mentioned it. He says it's no big deal and that all guys do it. I just can't relate because I haven't had fantasies about other guys since I've been with him. Not to say that I don't have the passing thought of "oh, that guys cute" but I don't fantasize about them! Any comments would be appreciated. Thanks.
