Just some q's...did you ever enjoy sex with your H? How long has this been an issue? Your post has a sense of urgency...is your H threatening to leave? Was the therapy your idea or his? How come it was such a bad experience?
I was LD for many yrs in my marriage, and looking back, I wish I addressed the problem earlier, not just for the sake of the marriage, but for my own sense of health and happiness as well. It's hard to feel sexual if you are feeling pushed or rushed...so try to relax and hopefully you'll soon be on your way to enjoying this part of yourself.
