That's odd, especially at your age. I doubt they just asked for your sexuality, probably more worded like "Does anybody here think they might be gay?". After all sexuality can be a bit wobbly around then O.O. Then again who knows.
And Mitch Hewer is the most gorgeous person alive IMO, but he's hetro and has a girlfriend, so so much for his character =P. He looks disturbingly like a character from Final Fantasy Versus XIII actually =).
