I do not believe that sex is a perfect picture of the real quality of a relationship. I believe it is only one aspect of a relationship. Our relationship has always been much more than sex. He and I became friends first. Our whole relationship is based on the trust we built. No secrets not ever.
The problem is definitely not physical. Our looks are the same now as they were when we met. Lack of trust is a total non-issue for us. This all started with job stress and I understood that. I honestly wonder if it just became a pattern for us. The job stress is still there but it has changed. He is with a different company and the stress is not as bad.
It has only been recently that the whole sex thing even bothered me. I am willing to bet even that will pass. I was just reminiscing about the wild romps we once had and wishing we could have one again. It was always so wonderful because of the trust. I could totally let go and have loving, wonderful, romantic sex or go for the primal, experimental, animal romp. I guess I miss it.
