Okay, I understand this thread is a bit of fun, etc, but I'm surprised by all the "I get / don't get vibes / my gaydar" etc posts.
Do people really still view sexuality in this way in 2012? If you behave in a certain stereotypical way you must be gay, and if you don't, you must be straight?
Some people need to open their minds a little.
Unless you know the person, the only way you can get the impression of whether or not they are gay is whether or not they exhibit any 'gay stereotypes'
Nobody's saying it's any kind of exact science
