I'm in the same boat. Sucks, doesn't it?
Well, there isn't anything wrong with you. My sex drive is generally higher than my wife's, but she's good enough to accomodate me when that urge comes along.
I don't have sex and it doesn't bother me none. I just jackoff and i am satisfied.
Males hit there sexual peak at 18...women hit theres in their 30's this might be why your husband isn't as randy as he once was. There is most likely nothing wrong but many things can contribute to lack of sex drive: diet, lack of excercize, hormones, and even interest in another sexually. Good luck and hopefully he is being faithful.
Was it always that way or is it a recent phenomenon?
How old are you two?
