Coincidence saidI am Asian; due to difference of culture, i find it hard to catch the gaydar of others especially american guys'.
p/s: Do american guys like Asian ???
I can't imagine why any guy here in the US wouldn't find you adorable. Naturally you're way out of my own price range at 19 (not to mention that I have a partner). But if you were old enough for me to see you at one of the Twin Cities clubs that I used to frequent when I was single, my age rule would be very strained. Or maybe our paths would have crossed at Loring Park during Pride Fest.
And no, Asian would be the last thing I would consider as an issue, or think a hindrance. Neither a like nor a dislike, just not something I think about at all. I don't know what most other American gays of European heritage like me think, but it's nothing of which I'm even conscious.
What I do think about are a man's eyes, and his attitude, his personality. I can look into your eyes and see your soul, which understandably frightens some men. (I also like to like to look into a guy's shorts and see if he's uncut, which is a plus if he is, but not a deal-breaker if he's not)
So no, Asian doesn't come into it, nor any other racial or ethnic factor, at least not for me. But then I'm an old guy, several generations removed from you, and I don't know whether we've gone forward in the US on these issues, or backwards. Lately I do wonder, and worry.
