Like most guys, I discovered masturbation around the same time I first saw a woman naked. My first experience with seeing a woman naked was Playboy magazine. My dad had a few issues and the first one I saw was December 1976. I read it cover to cover so many times I knew just what pictures were on what page and could get to them in a moment's notice! I kept it hidden and would get it out any chance I could so I could stroke my cock! Recently, I found a few images online from that issue and I couldn't believe how hard I got! My beautiful wife was upstairs in bed and I could have went up and fucked her, but I stayed downstairs stroking my cock and having all those old memories make me cum really hard! I'm hoping to find somewhere online to download the issue but here are links to the images I found!
