At 18 a whole world of pleasure was now available!! In my case I often used magazines. I was still living with my parents at the time. However it was hard to hide them so I also used to buy The Penthouse Letters Forum magazine, full of hot juicy stories. I loved Leg Show, with the stockings and thrills, there was Hustler, definitely! I used to even get off to the phone sex advertisements. I definitely stroked off in the bathroom to lingerie catalogs, lingerie ads, dirty books from the local adult books
