Some info on Peter/Matt:
Peter North started out making gay porn (as Matt Ramsey) because he was in debt and gay porn pays male performers more than straight porn. After he made enough to pay off his debts, he changed his professional name and crossed over to straight porn. He bottomed in the majority of the gay porn he did, including Like a Horse, Sizing Up and The Company We Keep, but also topped in films like Cousins. He did both in The Bigger The Better, playing a teacher who bottoms for one student (Rick Donovan) in the first scene and then tops another student in the second scene.
And Christy Canyon, a frequent co-star of his, mentioned in her autobiography that he did not like having his hair touched when filming a scene (as it "ruined his concentration").
