My husband sounds a lot like yours but your fears are just the "insecure women" in us that is always trying to tell us we aren't good enough. Truly, the problem is probably him and not you. A man's sex drive slows down as he gets a little older and so many things can effect it. Diet and exercise plays a huge part and if he has stopped working out and eating right and isn't getting enough sleep, his sex drive will totally disappear. Pair that with stress and he will be damn near impotent!!! Try to motivate him to workout with you and keep only healthy food in the house and it should help to get him some more energy.
