Thailand is famous for its seemingly gay-friendly attitudes, but homophobia certainly does exist. Lesbians are known as tom dee; they have their own hangouts and are usually less vocal and ostentatious than their male counterparts, or the theatrically inclined lady-boys (katoeys).
There are occasional Gay Pride-style events, as well as dazzling cabaret shows and beauty competitions for lady-boys, throughout the country. The same kind of nightlife that caters to heterosexual males is offered in Bangkok, Pattaya, and Phuket's Patong Beach. Venues range from gay bars and dance clubs, men-only saunas (bathhouses), and "pay at the door" parties. In Bangkok, the most popular male-only joint is the opulent Babylon men's club, off Sathorn Road.
