makeitrain...i don't really know what to suggest other than maybe you need to get some counseling. if i were you, i'd talk to my doctor about it, and let my doctor give me some advice on what kind of counselor would be most effective at helping.
i'm not sure if you have some separation issues that are affecting you sexually, or maybe you have some sexual issues that are affecting other facets of your life.
in any event, i'm guessing it probably isn't going to be real difficult to resolve, and you may be able to resolve it by yourself. you know why you feel the way you do in that you have been through your own life.
i'd love to be able to give you some help, but i'm not too smart on these types of things. all i can be is a friend. if you feel like sharing more about what got you in this situation, i'm sure many on here (including myself) will be happy to look at it and see if we can help with some advice.
