Have you ever been mistaken for being gay/lesbian?

I have openly gay family members who swore I was a lesbian when I was growing up. They all know I have Asperger's and were convinced I was too afraid to come out and was using Asexual as a cover for not looking for a partner. They know a pride parade would be misery for me because of the noise and the crowds. I have never wanted to date anyone and the thought of sex, not appealing. In high school, if you put a hot male or female celeb's picture in front of me, I would just roll my eyes.
