Before I got married, I was involved with 2 women in college, and the sex was overall very good. Then I met my ex-wife, who was a virgin, and we got married very soon after we met.
Sex was never good....it was never even okay....it was just hurtfully bad. We had 2 children. I felt really depressed, because I loved my family, and I was willing to stick around in a marriage without any sexual connection.
Finally, when ex-wife's inconsiderate mean behaviors began to boil over, I left. I was okay with no sex for 3 years (and bad/no-existent sex for 9 years before that), but I was not going to tolerate cruelty.
Now I am with a goddess who is very sexually compatible with me. It makes a world of difference...which I never imagined possible.
