Your wife is great to you but doesn't seem to meet your sexual expectations of her. If that is extremely important to you and she hasn't responded, there is no point in staying with her and cheating.

I know she would be better off without you.

This is a issue you should have resolved before marriage but very often we just don't foresee these serious problems.

Your wife deserves someone more compatible with her sexual appetite and so do you. And she also deserves someone with a greater sense of committment to her. She sounds like a nice lady and you sound like there are some things about yourself you aren't telling us about.
