Wow that...that makes a LOT of sense. You've brought up many many good points from previous seasons!

I also felt as though Wilson was trying to feel out House's opinions of non-straight relationships in the episode where he had the asexual patient, in the form of a bet. He read him facts out of a medical journal, and even stated that by them stating to the patient that his asexuality was only a cause of some sort of illness, that that would be akin to telling a gay person that they're really really straight.
