I listen to two different podcasts that have pushed HBO dong truther talking points. They both talked about how HBO never shows black dicks, and they used Euphoria as an example of HBO blatantly discriminating against black dong. It was the lakers series that got both podcasts talking about this. The first one started talking about it while recapping, I believe episode 2 when they talked at length about Spencer Haywood's wood but didn't show it. The other podcast started talking about it when they finally showed black dong on episode 9, I believe.
I have been seeing dick on HBO since I first saw nudity on TV while watching the show Dream On, the summer before my freshman year of high school, at 14 years old in 1990, and I don't remember black dick either, not even on First and 10 or Real Sex.
