Maybe I'm injecting too much of my own personal thought in this, sorry if so. The way I see it, my M was pretty stagnent in that department as well. I will say, after we had a a month long 'fight' we spent the next month having the greatest time of our M before it all fell apart (ie - tons of intamicy).
Knowing we could have those good times only backed my arguement that if she would (have) just given R a real fighting chance, I'm sure it would have been even better. BUT, only until I was fully convinced that OM was 100% hasta-la vista, la bye-bye, I would be very hesitant if not completely unwilling to engage in any intimate moments.
And, much that men aren't given the credit, I would suspect your H as I would can sense that OM still pops in and out your head.
