This is certainly NOT nonesense. At 10, I had an INCREDIBLE crush on a member of my own sex, and at 12, a doctor recommended that my parents take me in for psychological counceling because of my “gender confusion”.
Eh? I don’t see how a 12 year old can’t say that their gay. I realised when I was about 13 I think.
And check out this cute video of a 12 year old coming out: http://www.youtube.com/watch?v=ldNMqWkGuIU
More and more scientific studies point to sexual orientation being decided at birth.
