That wasn’t porn with actual intercourse
It was gauzy nude fake stuff
Like Lady Chatterlys Lover
So many folks been plagued with these rumors
Chuck Connors never did porn either gay or otherwise
He was straight and a patriot
Stallone did porn
Spaulding Gray did porn
There have been a few mostly guys and maybe a couple of actresses
Actresses did the couch
I was 13 and vaguely remember it as just being a silly movie so I would go with Wardaddy and say it was just goofy non porn.
Though I DO remember something like a cannon in the shape of a, er, man’s parts.
Maybe folks were into that in the ‘70s :)
Salma Hayek also did porn.
Actresses still are asked to do the couch. Probably actors too.
Don’t forget the Governator. He was the poster boy (and not only on paper) for gay men when he was in body building.
