Unhappy guy makes some good points.

The fact that you feel dirty and disgusting after having relations with another woman may stem from your earlier sexual abuse. Even if it doesn't enter you mind consciously, its there at least in your subconscious, and something you could discuss with a therapist.

There are some people who just plain don't like sex. They may like the closeness and cuddling, but have no wish to go further than that. There is nothing wrong with that as long as it doesn't come from an unresolved problem.

It sounds like you have some soul searching to do. You have your own answer, you just need to find it yourself.
