Seeking Seua Bai: Fluidity within Bisexuality in Thailand Prempreeda Pramoj Na Ayutthaya preedapramoj@hotmail.com Introduction Herdt and Boxer (1995, p.78) state that in the United States it is widely believed that “bisexual” is what gay men and lesbians call themselves before they come out. In this sense it would seem that whoever identifies him or herself as bisexual intends to hide their sexual identity as a person who is either gay or as lesbian in order to survive in a homophobic society. However, in understanding sexual identity we cannot ignore the sociocultural factors that influence the meaning of gender and sexual identity. Indeed, the meaning of bisexuality may also differ depending on the particular culture and society, and meanings may also change within any given society depending on the contextual factors of time and place. In this study I explore the self-understandings of Thai men who identify themselves as bisexual, but who have no intention of adopting a gay identity, in order to find out what factors may lead people to either identify or disidentify as bisexual. How do Thai men who label themselves as bisexual understand the meaning and practices of bisexuality? Furthermore, what arguments do they put forward to explain why they are not closeted homosexuals who will eventually identify as openly gay men after they “come out”? Thinking About Bisexuality
