Ugh, that is hard. It's hard to believe that he really things that every encounter should lead to sex. It seems perhaps that his feelings of rejection have elevated sex to an unnatural level of importance. I know that happens to me too. I liked Michelle's approach in the SSM book -- whenever her H asked for sex he got it. She went way overboard on the frequency. This effectively made it a non-issue and before long the requests were fewer and far between, because the security was there knowing that when he wanted it, it wouldn't be a fight to get it.
If you believe that H is in this "hypersex" mode because of a history of SSM, then I agree it will likely run it's course. Once you get the amount of sex you *think* you want, it can become less special and therefore less desireable. The push / pull dynamics of wanting sex and having it denied I believe elevate the importance.
I don't know if there's much you can do with that other than count on the fact that the A will eventually run its course. If it's only based on sex, it's bound to.
