How can you blame me... it's all right. I have been studying male nudity in main stream cinema and on TV for years and there are a lot of actors who have shown themselves frontally naked with both flaccid and hard cocks. There are prosthetics and they are hateful, but there aren't many. I don't understand which actors you're talking about in Boys S1, but I know Jack O'Connell perfectly and his first nude in Eden Lake, but we could spend hours here listing the guys who showed themselves naked, especially European (Spanish, French and Nordic ). How can we not think of Pierre Perrier's generous nudes or Yon Gonzalez's unexpected frontal in Mentiras y gordas or Elio Germano's erection in No Qualities to Heroes?
Using dentures is dishonest. If the actor doesn't want to appear naked he doesn't make the film. Point.
