Manu Bennett shows us everything in this TV show. We can see his butt in almost every episode, but in addition we get great view at his penis is the episode 5. He has a pretty big uncut penis. The late Andy Whitfield does not reveal his penis as it seems to have been digitally edited out, but we get to see his very nice butt at many occasions! In episode 5, Manu Bennett and Andy Whitfield fight naked, body against body. Quite a view!
In episode 8 of season 1, we get to see a lot of nudity. There is the much expected rear nudity of blonde cutie Jai Courtney. We see his butt as he is making love to a woman. We hope we will get to see front nudity from him someday. Episode 8 is also an episode where threee new slaves are brought in: Mike Edward, Daniel Feuerriegel and Ande Cunningham. We see rear nudity from the three of them as they need to be presented naked. They all three have nice butts. In addition to that, there is the much commented front nudity of Mike Edward. During that scene in the area where we see all three butts, we get to see Mike Edwards huge uncut dick. It's obviously a prosthetic. On the Blu-ray version of the show, there is an extra scene with front nudity of Mike Edward.
Craig Parker appears fully naked in the season 3 of Spartacus. He proudly shows there his thick cut penis. His pubes are shaved.
