how do you know if someone is gay by looking at them?
This excludes the femine males where anyone can easily see that that person is gay.
What I'm talking about here are the everyday people who do the same things as Hetero's like watch sport drink beer whatever.
People like Neil Patrick harris and Sir Ian McKellen come to mind.
How does a gay guy know that that person who he thinks is sexy is gay?
Or you walking in a mall and you see a guy there you think is handsome and want to hook up with, how do you know he's gay?
Or dont you know and you try your luck hoping the man will be gay?
