I have a wonderful, attentive, considerate, handsome, intelligent boyfriend. We've been together and exclusive over a year. My problem is that with EVERY man with whom I've ever had a relationship, I lose sexual interest within a very few months. Sometimes more quickly. I do seem to attract very nice, well-mannered, well brought-up, attractive men. Once we start to get emotionally close, I quickly lose sexual desire in these men.

Is this a general fear of intimacy and commitment? I am a sexual being and sexually uninhibited; but once a man gets close to me emotionally, I try my best to avoid sexual activity with him. I still can objectively see that he's a "hot" guy, but can't regain the attraction for him.

I have hurt MANY men due to this problem, and I need to know what steps to take to repair myself and change my behavior.

I'm 45, childless by choice, still very fit, attractive, and college-educated. I have broken five engagements over the years, since I was 19. I was raised by both parents, and both my sisters have been in healthy marriages for 25-30 years. I have plenty of good examples... why can't I follow them?

I appreciate any feedback.
