Yes, I think he's bisexual or he's a VERY open guy 'cause in one of his interviews, he said "it's flaterring when a girl or a guy tells you that you are hot" or stuff like that, i don't remember what he said exactly... Anyway, he mentioned very often in his interviews that little "or guys", so we can ask ourselves some questions, can't we? It's scarce an open-guy like that but he looks like he has a crush on Jensen, don't he? In any case I think so and he'll make a great couple with Jensen (although I'm not very sure yet that he's bi but maybe... ^^) Anyway, even if he is, he's still the same actor and guy and we'll still love him xD I hope I answered your question ;)
