On the off chance that this is a legit question- I'd say if you walk around alone looking creepy, thinking about how the girls only want your money, they can pick up on that. Also, on your last post, you mentioned you get attention from the older ladies but not the hotties. I had similar issues myself, my standards were so high I wondered why the best looking girls weren't running up to me, still not quite sure about that one, but my guess is the top girls still expect to be pursued somewhat, and also maybe a high season issue. I hooked up with a drinking buddy my age in Pattaya and hit the gauntlet, and the attention increased quite a bit. Maybe something about young backpacker looking guys running around alone thinking negative thoughts and not smiling?
Also, to relieve some of the obvious tension, head out to Soi SIX to the BJ bars. Don't worry if noone calls out to you, just walk up to a girl you like, buy her a drink, and she'll have you in a room with a trashcan full of used condoms
in ten minutes. Then rehit the gauntlet, make friends with some fellas your own age, and you'll understand why Thailand is so addicting.
Edit-that's what i get trying to give rather than recieve advice- It's soi 6 not 8, i only went once, not my thing...
