Is the 9th doctor who gay?

The Doctor has never really revealed his sexual orientation, though he appears to tend to lean towards heterosexual, if anything. Some claim he's asexual, but he has never said so. He has almost always, even in Classic Who, tended to prefer female companions, and compete with other males, even get jealous of them, so take that as you will. Since he isn't human, it's very likely he's capable of loving any gender though. He didn't protest Jack kissing him even if he might be straight, because he isn't biased, bigoted, or closed minded. He doesn't posses the same hang ups us humans have.
