I've read a lot of stuff that points to the number of older brothers you have as a man, can determine whether you're homosexual. Apparently, as a woman has more male children, her body becomes more skilled at treating the male foetus as a foreign body and feminises it by producing more and more female hormones. The odds that the next male child will be gay can be anywhere between 10% to 40%, but will become higher the more male children she has. This got me thinking, I have two older straight brother... and I'm gay. What about you? If the research is proved conclusive, would having brothers become a gay identifier, for better or worse means?
