When it comes to famous cocks, I'd say John Holmes had one of the most recognizable in porn history. While he only did one gay video - in the 70's, of course! - I recognized his massive dong the second I saw this video clip from Vintage Gay Loops. While I've seen people claiming that his penis was 12 or 13 inches, it was an actual 10" and 4" around, which looked even bigger because Mr. Holmes was thin. And here it is - John Holmes' legendary dick getting sucked from his only gay video!
