The problem could be anything. To be honest, the number of partners doesnt make a difference to me. Mrsinci, though younger than me, has been around the block more than I have because I am a scientist and we dont get laid much. But I dont care. the reason I dont care is that we have a loving relationship and we are both satisfied with our sex lives. And i think that is the point. if this chap feels that he isnt the best she has had (and it only takes one brief mention to make him think that, men being very fragile in the ego department) then hee will not take it well. Could this be the case? It sounds very sad , I know, but a few phrases along th lines of "no-one has ever done it like that", "baby you are the best" or "gosh you're huge" work wonders. they are almost always lies (apart from when said to me obviously) but that doesnt matter. Once he is happy and confident she can train him to do what she likes. Men are like dogs. pats on the head are a good training tool.
