The last time I had any kind of sex, and it probably wasn't that great, was 1998. A decade now.
We married in 1974 and I would say we probably averaged 1 or 2 times a year.
There was only one kind of sex he liked and if you catch my drift, it didn't do a thing for me. I fell into the trap of thinking if I was just accomodating to him, he would return the favor. Nada. Never did.
