Will Young, openly gay, is briefly seen completely naked around 40 minutes in the movie. We see his big ass, and although he is sideways, we can clearly see he has a very large and long uncut dick. We will hopefully get to see more of naked Will Young soon.
Towards the end of the movie, Aden Young is making love to a woman after having spread chocolate over her. We get a very good view at Aden Young's ass and then briefly at his uncut dick. He gets caught by his father-in-law (played by Hugh Laurie), so he reaches for a pillow to cover his genitals and we only get a second to view his full fontal.
