Blind LGBT people, how did you know you were LGBT?

Serious question: Was talking about "when we knew we were gay" with some friends and it seemed it always was when we were physically attracted to looking at someone of the same sex. But then the question came up, what if someone was blind? I know there has to be some same-sex attracted blind people out there, when/how/what was it that made you realize you were attracted to the same sex?
