I'm queer and my twin sister identifies as lesbian. It's cool, I came out in high school and she came out a couple of years later. I know identical twins have a higher chance of being queer if their twin is than other siblings. we don't know if we are identical but this supports that theory.
sometimes people react strangely or say stuff like "they should do research on you" or nature/nurture theories, etc. And of course it's been a little stressful for the family. Double the gays. :)
