So you need to read Michelle's book "Sexless Marriage." I would be willing to bet it isn't the fact he doesn't find you attractive.
I'm in my late 20's and sex drive was a big issue for my now ex wife, although it was a couple times a week for us. So age does not always matter. Working through the medical side right now
For a guy drive/performance issues are killers to esteem, so you need to be supportive.
In terms of fertility/testosterone, he can be placed on a combination of testosterone/hcg (keeps/improves testes production). If he is on hormone stuff, don't settle for anything less than an expert!
