Anyone have a sexless marriage?

We have been married almost 2 years. We waited until marriage to have sex, so we were both completely new to it.  He doesn't have much to work with and I'm a bigger girl so while we have fun and can get it going he can't seem to get it in the whole.  Or go off in it.  I think we eventually just made it a not important part of our lives and if we mess around great and if not oh well.  I just don't know what to do or if I'm the only person in the world who doesn't have sex multiple times a month and have a spouse who may feel the same.
