Hi Slogging ! I just arrived yesterday for a quick stay in Bangkok and found in my Lonely Planet addresses where you can go out and meet other gays. I think the gay scene is pretty lively here but maybe not elsewhere in the country, I don't know. In case you are in Bangkok but don't have the LP with you, here are a few names : Telephone, The Balcony, DJ Station, Khrua Silom, Utopia. The streets Soi Thaniya, Soi Prattuchai and Soi Anuman Ratchathon seem to offer a lot as well.
So I hope you'll find someone to have fun with ! And enjoy the rest of your stay anyway !!!
people are people
