In those golden days of yesteryear, there were strict codes of conduct in porn theaters and dirty bookstores. In the latter, it was thought rude to pick up a porn magazine immediately after another sticky-fingered voyeur had put it down. The girl in that magazine was still his girl. It was best to let some time pass and allow the couple to come to terms with their recent break-up. Then you were free to paw over Teenage Enema Bandits.
In porn cinemas, as in all cinemas, it was held inconsiderate, threatening and sexually provocative to sit right next to, directly in front of or (worse) directly behind someone when there were other seats available. It pains me to report that some lost souls went to porn theaters expressly to jack-off or to be jacked-off. I was never among their number. My preference was to sit far apart, all the better to enjoy the mise en scène. And, to avoid being hit by recklessly extruded seminal fluid.
Porn theaters, like strip-shows, were remarkably somber affairs. The men hunkered down to watch and/or wank in silence. No chitchat. No popcorn passing. Definitely no eye contact. You didn’t want to risk being recognized.
“Murray, what the hell are you doing here?”
Furthermore, a wisp too much eye-contact with the flaming Black fairies who walked up and down the center aisle, licking their lips while looking into laps, might suggest you were happy to let them get a lip-lock on your love-monkey. No. And again, no! Eyes straight ahead.
