Did you sleep with a lot of women before you came out?
Perhaps around 20, from when I was 26 to 46. Not too many, because during much of that time I was married and monogamous.
I was extremely confused & conflicted, why I didn't even date as a teen, much less have sex with girls. I began after returning to college in my mid-20s, dating to please my parents, planning my first dates and ending my virginity as methodically as everything else I did (I was an Army Officer on a break from active duty at that time).
I never really liked straight sex, though I tried my best to learn about it, and perform it to perfection. The best part was after getting it inside, because the vagina really does have the muscles, pressure and friction a man likes, obviously what it was designed for, when a woman knows how to use it. And the thrusting part is very natural for a man, what he's in turn designed to do.
But for much of the sex I was having homoerotic, closed-eyes fantasies. Dividing my mind between the nice sensations on my dick, and the thoughts in my head. I've never found a woman's body very sexually arousing, only a man's.
