What say you? I now say choice or oriented in unhealthy circumstances.
Incorrect. It is not a choice. No one "chooses" their sexual preference. There are a few people who are bisexual, but they are the really small minority.
Go ask some gay men or lesbian woman, face to face, if they "chose" their sexual orientation.
If sexual preference is really a choice, ask yourself, did I choose being straight? If I chose being straight, when did I make that choice? Why did I make that choice? What were the factors that went into that decision?
Chances are at puberty your dick signaled to you it liked pussy. It didn't like other dick. Thus you "decided" to "choose" being straight. With gay men, their dicks signaled it liked other dicks and it did not like pussy. Ditto
for lesbians, their pussies liked other pussies, not dick.
