Game_Over:

I doubt very much that you are lousy at sex. This is RARELY the cause of SSM. The problem could be either the relationship, or with HER (most likely). You sound like most guys where the sex went downhill shortly after marriage. Women get a chemical boost for 2-4 years in new relationships that give the apperance of a HD women. These chemicals act like testosterone, they make her HD. Then they wear off and the REAL women comes through, and it is NOT good. Her sex drive and her sexuality can likely fall off the face of the earth. Until she decide that SHE wants to find it, all you can do is work on you.
