I stopped watching porn in March of or May of 1985. I can't remember which month, but I was never a big porn viewer anyway.
That being said, I urge EVERYONE to watch this porn movie:
Reel People, from 1984. Sometimes it's listed as 1984.
Go to the third scene with "Chuck".
I believe this man knew Primemuscle. If you listen to what city he is from, you will understand why I think this.
