Well, I would say my first time was when I realized that I am attracted to men when I was in high school. In fact, I was very sure from the beginning that I am attracted to men from those days. I never was attracted to girls ever. I could make out that other guys were also attracted to me the way I was attracted to them. It was always my choice and nothing happened accidentally as I was very aware of what I was doing. .it was something that happened naturally without much effort.
