Mr. Johnny Wadd! You're Wanted on the Set!

John Holmes, also known as Johnny Wadd (this was the Hollywood nickname that stuck, based upon the lead character he portrayed in a series of related straight porn films), was one of the most prolific male sex film actors of all time.  The man began his career in smut thanks to his large cock.  which he showed off via gay photos and some loops.  Exactly how many men that John had sex with (in film and also as a private agent/hustler) remains an unanswered question. 

In 1971, Holmes' straight porn career began to take off with a porn series built around a private investigator named Johnny Wadd.   He was marketed as 'the guy with the huge cock' at the right time in history, as porn movies such as Deep Throat became sensations with the general public.  It's ironic that straight men felt comfortable being fans of another man (Holmes) because they wanted to look at his cock, without even a flinch of homophobia, but that is exactly what happened.  To this day, oftentimes the homosexuality component, prior-to-and-after his stardom in straight porn, continues to be downplayed or even ignored in his life.   No definitive measurement or documentation verifying his cock to be 13 inches exists, leaving its exact size unknown.

How would his hetero audience react if they had known what Johnny did with that cock with other men?  After all, straight guys treated him as something akin to a a sportsman who they were a big fan of.  Just as they could brag about a star athlete's stats, they knew Johnny's (claimed) inches of manhood and enjoyed watching him screw it into his female partners (a popular feature that sold well to his straight male fans was Johnny stuffing it into a girl's anus with her face visible as she's experiencing taking it.  Swedish Erotica 87 - Stuffed Rears is an example).  During his time in porn, Johnny had appeared in over 2,500 adult loops and pornographic feature movies during the 1970s and 1980s.
Near the end of his life, Holmes was a world away from where he had begun in the business.  He attained notoriety for his involvement in the Wonderland murders of July 1981 and eventually for his death from complications caused by AIDS in March 1988.  He was the subject of several books, a lengthy essay in Rolling Stone, two feature-length documentaries, and the inspiration for two Hollywood movies, Boogie Nightsand Wonderland.
