Firsts tend to be memorable events. Even 40 years later...
I was home from college for the first time; winter break after living in the dorm for 5 months I was back in suburban New Jersey for the first time. I had two things - a baggie of weed, and ID that said I was an adult. My hometown had something I could now visit - the Adult Bookstore!
I remember it as a sunny day. No one else was home, so I stepped out on the back porch, smoked a joint and was buzzed. I went back to my room and for some reason, figured that it was important to leave my underwear home. When I was set, I got in the car and drove the ½ mile or so and then parked my care. Never dawned on me that I might want to park carefully and strategically so I wouldn't be seen - I learned to do that later.
I opened the door and it was as if I was in another world. Garish neon backlighting on the walls; display cases with things ranging from handcuffs to dildos; aisles of books and magazines with naked bodies prominently displayed - this was new! There was also a smell to the place - a mixture of cigarette smoke and something undefined.
Nobody asked to see ID, so I just went in and assumed that my newly grown mustache was enough. I suspect that my status as "new to the place" was probably obvious to the regulars - gazing wide-eyed at magazines featuring every sort of sex act I had read about. (Remember, this was before the Internet and the advent of "all porn, all the time" that we now live in.) I remember that I was hard as a rock within minutes, and that I spent what seemed like forever browsing through magazines. There were seemingly dozens of magazines just featuring boobs! And then I found the hard core magazines and I was aching!
Even back then, I was drawn to written pornography. That was back when there were series' of paperbacks, with illustrated covers and titles like "Steaming School Teachers", "On the Wrong Side of the Tracks" and many others. They had shelves of paperbacks with titles that were as arousing as anything. I haven't seen much of those in the last few visits in recent days, frankly.
At some point, I discovered their movies. The technology we have now didn't exist - they had a master list of booths with titles, and then each booth would have a card. One film per booth. To see something else, you needed to change to another booth. Yes, I know, primitive stuff!
