A gay subtext? (spoilers)

I have know idea how Cohen feels about the gay issue, but there sure is some innuendo of the theme here. The villain is out of this world, hates it, looks like a flamboyant person and has a vagina and wants to mate with a dude. The good guy has not one but two chicks and he's not comfortable with either of them especially fearing fatherhood. Not to mention that when the ET asks him to mate, he hesitates for a sec or two.
Then again, all of this could be accidental, of course. Just saying.
