Caroline asked him if he was bisexual in a discussion about his porn and how he must be open-minded. He replied that he doesnt want to do gay porn but that there are lots of animals in the world that engage in same-sex intercourse and that humans are simply sexual beings but he doesnt like the 'bisexual' tag and that obviously people have a preference.
Seems like a long-winded answer that he is bisexual but prefers women
