Nicholas D'Agosto: Hustler, Sex Researcher, Cheerleader

Dirty Girl (2010) is about a promiscuous straight girl who goes on a road trip to meet her biological father.  She takes her chunky gay bff, who is trying to escape his violently abusive parents.  It has three things to recommend it:
1. The gay bff (Jeremy Dozier) is chunky, not svelte (although still a swishy stereotype named Clarke).

2. He actually has sex, with a hitchiking hustler (Nicholas d'Agosto).

3. He doesn't turn straight at the end.

Jeremy Dozier has slimmed down since. His other movies include Bad Behavior (2013), about a babysitter fighting off the bad guy, and Rock, Paper, Scissors (2013), which seems to be about three friends playing Russian roulette.

Nicholas d'Agosto has taken off his clothes in a number of other movies, mostly teen sex comedies and horror spoofs such as Drive Through (2007) and Extreme Movie (2008).  

He is naked most often in Fired Up! (2009), in which two goofballs (Nicholas, Eric Christian Olsen) sign up for cheerleader camp in order to get girls, but find that they actually like cheerleading.  They have a swishy gay-stereotyped roommate (Adhir Kalyan)

Nicholas is currently starring as Dr. Ethan Haas on Masters of Sex (2013), about the homophobic sex researchers Masters and Johnson.  There's a closeted gay character.
