Wow, what an interesting thread!! It reminds me of a conversation I had a little while ago when someone asked me why my friend 'chose' to be gay. To which I replied, 'when did you choose to be straight?'. Sexuality isn't a choice, and nor is gender. Your anatomical genitals don't dictate who you are as a person, nor do your chromosomes. You don't choose who you are, you just are. Whilst I'd love to get into a debate about epigenetics, I'm not sure it would benefit this thread! But for those that are interested, I highly recommend reading up on the topic!
