When I was 19, I had a female friend who was a year older than me and she introduced me to some of her friends. One of them, a girl that had been around the block a few times, took a liking to me.
She popped my cherry (yeah, I know i was kinda late), and the day after, I was sitting with my best friend and my female friend, and she started going on about how her friend had told her I was huge. It was kind of a great moment, because I never knew I was big, but had always hoped.
After that, my friends started calling me "BAM", until I had to tell them to stop, because it was getting a little out of hand.
