Of all the questions I get on this site, How do I know I'm gay? is probably the most common.
Often teens ask this because they are genuinely curious and questioning their sexual orientation.
Other times, they are pretty certain they are gay, lesbian or bisexual, but have been told by someone else that they aren't.
Guys might hear, "You can't know you're gay unless you have sex with another guy."
Girls sometimes get, "You're too young to be a lesbian."
Neither statement is true of course, but if you hear something like that often enough, the natural response is to wonder if there might be some truth to behind what you are being told.
That isn't to say wondering isn't normal. Plenty of people think long and hard about their sexual orientation before they actually come out to themselves.
But the process of figuring out if you are gay will be a lot easier if you don't buy into a lot of the misinformation and mythology about what it means to be GLBT.
