Gee, I can't fathom why your wife might find you unattractive. You sound like such an attentive and considerate lover. /sarcasm.
For your info - I compete in bobybuilding, am in tip top physical shape. You know nothing about my life, and I am talking to you about what goes on in a normal guys head.
If you think a guy really wants to hear about how his mother is not nice enough to his wife, someone is lying to you terribly.
