MM, I want to add a word of warning in addition to what SM said. Beware of sexual burnout for yourself in your search for fulfillment.
I think that you want what the rest of us want, and that is to simply be wanted. I think that is what you need from your husband. His desire may never match yours, but if he can look at you and you see that he wants you, isn't that good enough? I know you aren't quite there yet, but when you do get there, it will kill a lot of worries about the future.
If it is just over the top mind blowing sex that you are interested in, I can tell you about my experience.
I look back at all the people I had 'just sex' with. In my mind, it is nothing more than a pile of a thousand limp naked bodies in a glass cube. I can find no definition for anything in it. It is as empty as a fart, the only briefly lingering substance of it being a regrettable stench.
All the best, -NOPkins-
I will ferret out an affair at any opportunity.
-An affair is the embodiment of entitlement, fueled by resentment and lack of respect. -An infidel will remain unreachable so long as their sense of entitlement exceeds their ability to reason.
