Beach boys and muscle boys are permanent parts of gay erotica. Sadly as the cover copy shows even some of the men who produced gay porn were homophobes:
Miami Beach and Gay Tourists —- Suntanned muscle boys for sale to perverted tourists. See what happens in these gay Florida fleshpots, and the darkened beaches and palatial private homes. Follow the adventures of young Corky in the fairyland that is Miami Beach during the gay holiday season. Bikini Boys … Queer Beach Queens!
The cover artist is Gene Bilbrew, best known for his heterosexual fetish work.
