I believe that both factors play a part in heterosexuality and homosexuality. Genetically you can be born with less testosterone than the average male and that can lead to famine traits like flamboyant talking, dressing, and make up. Vice versa for women usually homosexual women have more testosterone when they are athletes. Women working out produce more testosterone have muscles similar to a male and isn't a social norm. Usually they will date a women because a male doesn't want them because of their athletic physique. So that is my take on essentialist and constructionist, they both can play a part on sexual orientation. I honestly didn't know it went this deep, I appreciate being in the field of sociology, you get to learn all the possibilities of people that aren't commonly known by the average person.
