Then BKK has it: a fair lot of gay disco´s aimed at younger guys (and their admirers, tolerated as sponsors). Best known of course this DJ in Silom soi 2, also the big one near Ratchda (FAKE). And of course the few spread in the year ´white/rave parties´. JUst go there and you will soon have contacts.
Have not been to Pty for many yrs so others will know that biggest brothel in the world by the sea better.
