Only by the guy in the mirror....

Na, not really, I think one time while at Starbucks some gay dude was hitting on me, not trying to be stereotypical but he looked like a total fruit wearing a scarf, (what guy wears a scarf?). He tried to say hi to me, I just pretended I didn't hear anything. That's about as close as it has come, but nobody has ever just outright asked if I was gay, so I guess I must be doing something right if my gaydar is broken.
