What porn magazine rated its articles by states of erect penises?

[DeanGreen]

Please help to jog my memory loose. I am thinking it was Playboy. I don't buy and porn mags. I do remember seeing this in one. My brother was into all kinds of porn you name it it was likely that he had a magazine or web site. I can't ask him. Someone please help me out.
Thank you
Dean

Hustler used to rate movies with an erection scale, if that is what you're looking for.
