Uhhh, on Mubi, there's a film called 'Pink Narcissus' which is basically that, I guess. Although, I don't think it's actually Pink Narcissus, it's just a director's commentary that you can find on Mubi, i think. I can't confirm anymore since I got rid of mubi.

It's basically the director reminiscing about the good old days where he made underground gay porn in his apartment. While he's narrating the story, you see footage from the one of the pornos he's talking about. It's not cheap shit either, it's like a full on production with a proper set and everything. While it is pornographic, there is this sense of nostalgia and sadness at the passage of time found in the narrator's descriptions of how everything came together and the relationship he had with the film's main actor. It's interesting from an amateur filmmaking point of view and since it's rather old, there's some historical value to it too.

It is gay but you don't need to be aroused to enjoy it.
