Legendary photographer/anthropologist Charles Gatewood, under his FLASH VIDEO label, had a successful line of VHS documentaries called Erotic Tattooing & Body Piercing. It used to be taken for granted that people who were into heavy body piercing were more likely to be involved in alternative sexual lifestyles- the roots of the piercing scene were firmly embedded in the gay leather scene and was popular with straight/bi S/M players who used their bodies to display their kinks.
Since tattoos were usually kept hidden in the early years of the scene they provided an avenue to take that concept- using the body to display kinks- quite literally. If simply being tattooed could arouse an erotic response it would only make sense that sometimes the tattoos themselves would be erotic, like the mermen on piercer/tattooer Sailor Sid Diller’s legs.
This photo, scanned from a 3×5 print dated 1978, features Alan Oversby tattooing a Tom of Finland styled Leather Man on Sid’s leg. Sid’s legendary tattooed/pierced penis and scrotum are also on display.
