I hear a theory, a idiotic one, about homosexuallity. It is simply this-when an egg is split (twins, boy and girl) the female gene accidentaly gets in the male DNA. Resulting in confusion about sexuallity.
I believe this is SLIGHTY possible, but actually leading to gayness is absurd. Maybe give a little confusion, and act differently but please...Oh, and not every gay person in the world is a twin...explain that?!
