Well, he had his chance to tell me not to speak so I will let it fly. Flip, you don't have to read this if you don't want to.
Jealousy is a completely natural emotion. It is instinctive. If someone is not jealous to some degree then they are just not wired right.
Some people say that you need to know your partner's ****** history. I think in most cases it does more harm than good. You end up dwelling on things that your partner has long since forgotten as a practical matter. the only reason she even thinks about it now is because you constantly remind her of it in some form or fashion.
I think most men would be disturbed at the image of their woman having *** with multiple men at the same time. I don't think that is a good indicator that you are more insecure than anyone else.
You tend to think that you resent her more because you denied yourself ****** experiences when you were younger and all the while she was doing whatever.
Maybe, but even if you were a ***** monger back then, I think those images would still be eating at you.
You have made the mistake of asking too many questions. She has made the mistake of answering them. Perhaps you need a fresh start with someone else and this time just worry about the present and not the past.
If you want to see if a shrink can help you work through these "issues" with this particular girl then fine. But don't think that you are somehow abnormal because these things bother you.
