Reminds me of books about kids I saw in a 1970s porn shop.
Yes, I went in one-ONCE! and that was enough for me. I thought it was an auto parts store. THE BODY SHOP in Tulsa OK.
I had a somewhat similar experience. My cousin and I snuck into a porn shop as young teens and bought a book about sexual perversion written from a psychiatry perspective, a choice inspired by a family subscription to Psychology Today. I don’t think we got past about 3 pages, and it didn’t have pictures. LOL. It was truly a life changing moment! Too bad more people didn’t have it cross their hands. We might not have today’s issues, the water being slowly turned up on us.
