I remember when I first went to an adult bookstore back in high school -
The gay section was divided into "Gay" and "Anal" like fucking was extreme even in gay sex. Each booth in the back had a choice of 2 movies to pick from and a switch so you could change them. Thankfully there was always a straight movie playing with a gay movie as I would have been too afraid to go into a gay booth.
What was funny was when you came across a movie that was obviously shot on silent 8MM film and they had dubbed in sound and music. The people not even talking and the soundtrack going "oh yeah suck my dick" - LOL
