Pretty interesting video:
Personally, I believe that homosexuality is indeed something one is born with. as for the biological explanations why how people become gay, well, I'm beat!
People may grow thiking they're straight but contrary to people's belief, people don't just 'turn' gay... people hide and when they get enough courage they come out... that's the long and short of it.
And no, I don't believe in ex-gays... once you've tasted c**k, there's just no turnin' back! look at all the whacked "straight trippers" out there... married or involved with a woman and secretl fooling around with guys....
haay, god help us with our struggles
