I used to have a g/f who was a nympho. At first it was fun, but after a few months of constant sex it became really, really old. All she wanted was sex. Non stop. And she was selfish about it, no oral, anal, dress-up, nothing. Just straight in and out sex for hours at a time until she had cum thirty times or so, and then she had to go. I suspect that the OP's husband has a low sex drive - virgin when they got married, and that he just isn't interested in having a vagina constantly being shoved in his face. Time to hit the road...and I bet he would be grateful for the peace and quiet.
I see that you haven't posted since. What did you do? Stay, go, find extra-marital fun? And what was that fun? I went to look at your Symtoys link. Good site with your interests. Let's talk.
