Jake Gyllenhaal finally gets naked! We had been waiting for a long time and did not get it with Brokeback Mountain. In Jarhead, there is very clear back nudity and dark front nudity. At the beginning of the movie, we see Jake having sex with a girl. We can see his back and ass and with the movements, we can clearly see his ball and thick dick flopping! Then there is a shower seen, unfortunately back lit, where Jake walks naked towards the camera. Finally there is a third naked scene, as Jake is naked wearing only a santa claus hat, actually 2 of them, one on his head, and the other one on his genitalia. During this scene, we can see his butt a lot as he is performing a sexy dance. We can even guess he has a hairy crack!
