My gaydar needs a tune-up

I often tell people that my gaydar is terrible, and it really is. I thought this girl was a lesbian, and she has a boyfriend. At a party, a girl came in with a gay guy who turned out to be her boyfriend. Those are just two recent examples of my folly.

So how did I get 85% correct on OKCupid.com's Gaydar Test?
You personally got 17 of the 20 people correct and were better at recognizing girls than guys. Overall, you guessed better than 94% of all test takers.

Gay or Eurotrash? (I think this is a line from the Legally Blonde musical)

The point is, not all gay people can be stereotyped or easily discerned as gay. And that's it. Good night!
