A.) How old were you when you lost your virginity?
B.) How old were you when you masturbated for the first time?
Being a shy kid I didn't lose my virginity until I was 19 years old. It was a simple hook-up with a co-worker and only happened once. I didn't have sex again for a few months.
I actually masturbated to completion the first time when I was 17 years old. It wasn't until a month or so later that I realized how absurd it was that I had started so late. But, like I said, I was a late bloomer.
