I remember reading John Money's 'Sexual Signatures on Being a Man or a Woman' and wondering if that was really possible. Nurture wins over nature. It turns out wrong and nature eventually won. The book is still available on Amazon. Whenever I hear anyone argue homosexuality is a choice I always ask that they switch hit, so far no one has reported back. I wonder why.
"On March 14, 1980 -- when "Brenda" was 15 years old -- Ron and Janet Reimer finally told their child the truth: "She" had been a normal boy until a terrible act of medical malpractice had destroyed his penis. "Brenda" was relieved. He wasn't crazy, after all; his growing sexual interest in girls suddenly made sense; everything made sense. "Brenda" insisted on immediately reassuming a male identity, and he did so with remarkable ease, despite having neither a penis nor testicles. He chose the name David, because he felt that his life so far had been a David-and-Goliath struggle. "Brenda" is now David Reimer, happily married and the adoptive father of three children. He is proficient at automobile mechanics and enjoys watching televised sports."
'David Reimer committed suicide in May, 2004. He was 38 years old.'
