Is being gay biological, enviornmental, or a combo of both? i am gay and always wandered this.

Debate: There have been studies done with MRI and pet scanning of the brain that has shown symmetry of the brain of homosexual people is similiar to that of the opposite sex and respond differently.It is uncertain whether this occurred after environmental factors made the person homosexual or if it is the cause of homosexuality but the researchers who did the study said "if you are gay you are born gay.".

It's what you are: While this continues to be a source of controversy in the political arena, overwhelming scientific evidence indicates that male sexuality is determined by genetics & the intrauterine environment before birth. It is part of your unique individuality & being yourself is key to health, happiness, & finding love. It's scary for an 18yo. You show courage even asking. www.youtube.com/watch?v=z6zph97qyd4.
