My bf actually has a lot more girl friends than guy friends. At the start of our relationship I felt completely fine with it but then he started telling me all the details, both sexual and romantic aspects, of all of his regular girl friends and ex's that he's ever had something with before.
At first his reasoning for telling me everything was because he wanted me to know that he's had a darker past in relationships before and didn't want me finding out another way but then as time progressed he just started dropping comments about sexual experiences he's had with others for no reason. And that stuff still plays on my mind even a year and a bit later.
It's a weird feeling because I appreciate his honesty and I know he's faithful but at the same time I just wish he never told me any of that so then my mind wouldn't constantly be on it. I think if it wasn't for my retroactive jealousy I would feel more okay and comfortable being around his friends.
