how do you feel about "gaydar"?

Some people believe in it, some people don't... But I'm here to tell you - it's real. I have always been able to tell if a guy was gay or not. No, I don't look at people and use stereotypes or their clothing and go "oh he's gay". I believe that, in general, gays possess certain personality traits/types of body language that straight people just simply do not have. To be honest, most concepts of a gaydar are pretty hard to put into modern language... It's not based exclusively on masculine/feminine aspects but moreso vibe, expression, personality, body language, confidence, and to an extent, appearance (people deny that appearance matters but psychologically it always will have some effect)I have known/met many extremely masculine guys, even those who had girlfriends at the time. However, something about them just "signaled" to me that they were actually gay.... Low and behold, after a while, I found out that ALL of them were now gay or bi!How do you feel about the idea of a gaydar? Any interesting studies or experiences? There is no "definite" way to prove this or gauge (or should I say gayge) how accurate someone's would be, nonetheless, I find it very interesting and would like to know how others feel/relateBTW, I'm gay so please don't get offended and turn this negative! (Damn you, Internet)
