I don't believe gaydar is an urban myth at all.
Jack and Randall KNEW, it was completely obvious.
I know many many guys who can look around a room and say, gay, gay, gay, straight, straight, straight, closeted, gay, straight...etc.
They are almost universally correct. Me, I can pick up on the vibe. Sometimes it takes speaking with someone a bit--there is a cowboy with manure on his boots out here [lol], the real deal. Nobody would ever think was gay unless he told you, yet I picked it up the second we said hello in the Wyoming pasture where he was feeding cattle. It's a 'vibe'.
Perhaps Scott is right--the sex drive has us pick up potential mates. It's quite possible, which would explain gaydar logically. We pick up on the 'mating ability' roflmao.
I'm wondering if that might be it because I'm bi and have had this talent where I could tell instantly if a woman was menstruating. I never looked for or developed such a talent it was and is simply THERE. I had a friend who could do the same thing, and yes, we sometimes DID ask if we knew the girl would not get offended. We were never wrong. By the way, he was completely straight and the most successfull 'stud' I have ever known lol.
The guy I fell in love with, the first time we set eyes on each other it was a mutual HOLLLY SHEEEIIT!!! moment if there ever was one. I knew there was something there even though nobody else did. He knew there was something in me. neither of us thought the other gay. After shaking hands--there was literally a static charge, a visible spark! -- I knew he wasn't gay at all but wondered if he was bi or might possibly be deeply closeted. He wondered the same. He turned around, not a word, and I KNEW he was bi. Vice-versa held true as well.
We just knew.
That potential mate idea of Scott's may well be it. Any thoughts?
