Two Rules
(1) Your pick has to be DVD length (aka 60 min +), there's a lot of bad titles out there but i want to focus on the ones, you can or could of find in a store (online or in a adult shop), the ones where you have a copy (DVD,VHS,BR and so on) that you desperately try to hide from family

(2) it has to be gay porn (MxM)

Lets this one out of the way, all the parodies that combine "Insert Known and Relevant Things Here"  with "A XXX Parody" in there title
Confessions of a Male Groupie - How I Learned to Stop Worrying and Love the Electric Banana: well now, that's a title and i think speaks for itself
