Don't think it can just be "willed" to go away. It just might not be so simple.

I have been married for 25 1/2 years and my wife's sexual past IS AND ISSUE TODAY! There is no such thing as a free ride. My wife is literally unable to truly get to any reasonable level of intimacy associated with sex because she completely took a big dump on sex and still has no clue what it truly means as a part of a committed relationship.

When there is a lot of uncommitted or "casual" sex, oxytocin is released by the woman with pleasure and orgasm which is the "bonding agent" that is supposed to help bridge the the reality period immediately after the honeymoon period. When a woman "bonds" with a bunch of guys, bonding ceases to have any meaning at all. Please don't be flippant about this. My wife and I have lived it for almost 26 years and until you have done that, please don't "school" me on anything related to this. It can be an issue and you should keep your eyes open. The typical situation is that the "13 guys" translates in "girl algebra" to "25 guys." Yes, that was a reality for us too. Take care and good luck. Don't waste your life if you believe that the cause may be lost. I wish I had been given that advice...
