My cousin was a play boy so he would always be bagging some cute little slimmy, he would provide me with all the tips and tricks.
My father also knew a gigolo who had plenty of time to share the game with me. Besides that, I was a natural, I read a lot about the Marquis de Sade, Bukowski, and Hemmingway, growing up, so all of it was a game before I even knew the game was "real".
