Is homosexuality real? Is heterosexuality real?Or Are these just labels Applied to explain a certain behavior that in its application subconsciously prescribes others to feed into the label?If one enjoys sex with people of their own sex, are they gay? Or are there the same amount of orientations as there are people?If there were hypothetically no labels, would people who identify as straight have more sex with people of the same sex? Would people who presently identify as gay have more sex with people of the opposite sex?
