Kid. Listen. Yes - you can adapt or change your BEHAVIOUR - i.e.. A homosexual man can adapt by having sex with a woman - but does this change his primal urge to have intercourse with another male? no. I agree, the brain can adapt and learn - but rarely do an individual's basic primal instincts change. Have you ever known a short-tempered, intolerant, insecure loud person to all of a sudden CHANGE into a sweet, soft, nurturing, warm and tolerant person? The BEHAVIOUR changes. Sweetheart, there are scientist's who study the brains of homosexual individuals and they have PROVED that there are large chemical differences in the hypothalamus.
We are hardwired the way we are, from the moment we come out. People can change. They change their reactions or behaviours - but I cannot make the lady with MS, not have MS. The 7 year young boy with treacher collin syndrome - CANNOT change himself to not suffer from the syndrome. He can adapt to his syndrome and change his lifestyle behaviour to learn how to cope with it better, but it doesn't change that the bones in his face are different.
Who am I to say that sexuality is different? OK. Why don't you jerk yourself off to something that repulses you? i.e.. Imagining your Mom and Dad getting it on. Can you change your brain to all of a sudden find this image appealing? If you are successful, I will stand up and applaud you.
Why can't I compare height, weight, eye colour and fingerprints to sexual orientation? We are all born with each - it is predetermined.
