Koschei gave Harry an amused look. "Humans and their labels. Harry, there's a very large gender skew among my people. Ninty percent of us are male. And... really, I enjoy the sex with Romana as much as I do the sex with Theta. The emotional aspect of them both is different, but equally as important to me. My only care when it comes to a bed partner is that they are a Time Lord, and not terribly young."
He sighed, chuckling softly. "The short version of that is, no, I'm not gay, but I'm not 'straight' either."
