Homosexuality tends to run in families. The prenatal thyroid theory suggests a relationship between thyroid disease in mothers and same-sex attraction in their children.

my brother is gay.

The proclivity towards homosexual behavior is typically activated via sexual abuse by a parent or older sibling.

Are you the older or younger brother?

I'll just assume all that's true I don't know I have the belief that people are born gay and it's not some learned/triggered trait.

I am younger, however, my brother spent a significant amount of time in a foster home and away with other family members. My brother and I do not have the same father. My brother only recently found out who his real father was, so perhaps it runs on his father's side of the family.

He claims there was never any sexual abuse when he was younger.
