Advance review from another site:
Nicholas' body is on frequent display throughout the first half of the series, including several scenes in tiny speedos both swimming and lounging around a hotel room. He has several nude scenes, but only one of note being a full body rear shot in a shower, but behind a frosted door. You can see, but it's not ideal. His other nude scenes are shot so you don't really see anything (obstructed frontal getting out of shower holding towel in front; his back in prison shower - full frontal and rear extras; naked in a closet curled up in a ball; naked in shower with Cooper, but behind this same frosted shower door and Cooper in front).
Cooper, however, goes full frontal and rear in a prison shower and we also see his butt in the shower scene noted above with Nicholas. He's got a couple more (side nudity sitting on floor of shower; getting blowjob in prison shower but shot from above so you can't see anything). I think that is it.
Javier Bardem side nudity and Brandon Santana rear in shower when Cooper is frontal.
