My endocrinology teacher said studies report the following:
7% of people are one hundred percent STRAIGHT
7% are one hundred percent GAY
the rest is one huge MIX
I am straight. Never felt attracted to a woman, or a RL one, at least, but I wouldn't say I am absolutely sure I am part of those (7%).
But that is just one of many theories.
I would say likewise. Never felt attracted to a boy in real life. Only girls, but I don't think that makes me as straight as an arrow.
Watch him blow this tie-break.
