Viewers of the movie are split on the answer to this question. Some say that, yes, Chase (Cam Gigandet) was gay or, at least, bisexual, and cite as evidence his intake interview in which, when asked whether his sexual partners were male or female, he hesitates before finally saying, "Female." They also refer to the scene where the prisoners are showering following their arrival, and Chase orders Oscar (Jason Lew) to turn around so that he can see his private parts. Other viewers argue against this idea, based on the same intake interview in which Chase reveals that all of his sexual partners have been females. They also point out that he masturbates to pictures of women, not men, and explain his attempted rape of Oscar as the actions of a sex addict who needed to satisfy his urges by raping and dominating a weaker prisoner. Probably the best answer to this question, since the film-makers aren't talking, is that Chase was obsessed with sex (i.e., stopped counting his partners after the age of 17) and did have a latent tendency to humiliate and subjugate those he saw as inferior, e.g., women, homosexuals, and prisoners (witnessed by the flashback of his sexual performance with the girl in the bar and his obvious delight when Barris kicks over Travis' chair and pees on him). These tendencies were then brought out under the conditions of the experiment, just as the experiment brought to the forefront certain characteristics in Barris, Travis, and others.
