CA1 Online-Only Material: Supplement AFarang (foreign, Caucasian) men have played a significant role in Thai society for several decades as sex tourists and, more recently, as farang sons-in-law, men who marry Thai wives and often settle down in rural Thai villages. While both of these phenomena have received considerable attention, in neither case have the experiences and motivations of the farang men involved been adequately examined. Based on fieldwork in Bangkok and the northeast region of Isan, we examine the relationship between emergent masculinities of sex tourist and son-in-law at a societal level and the transient subjectivities of men who experience them. Anthropological theory regularly conflates subjectivities and the cultural and social formations, particularly "identities," that shape them. On the basis of our analysis, we argue that a distinction between the two is needed in order to adequately theorize changing masculinities. The ways in which men's subjective experiences of masculinity change are different from the ways in which culturally shared, socially constructed, and politically-economically facilitated masculine identities emerge. We caution that evidence of the former-transient subjectivity at an individual level-is not evidence of the latterchanging or emergent masculine identities at a societal level.We met Patrick at a café in a small northeast market town in Thailand, where he was drinking beer and whisky alone at midmorning. 1 Speaking slurred English with bits of Thai mixed in, Patrick related a lovelorn tale of woe about his "mia suay mahk mahk" ("very, very beautiful wife"). He told us how he had spent some 5 million Thai baht (∼US$150,000) over 4 years living with her and chasing after her. He had married her, built a house in the northeast region of Isan, given money to her parents, and bought her large amounts of gold. He had, by his account, done everything he could to get her to settle down with him in rural Isan. But at the urging of her parents and sister, she had chased him out of the house he bought for her and gone off to Pattaya to find a new, better farang (Westerner). Patrick was a large English man and former soldier in his early fifties with several adult children from a previous marriage in England, whose names he had tattooed across his body. He was now living primarily on a military disability pension. His "mia suay mahk mahk" was a 23-year-old woman from Isan.Patrick is one of tens of thousands of farang men making lives for themselves in Thailand. 2 Across the agricultural hinterland of Isan, in nearly every village, are at least one or two ban farang (literally, houses of Westerners). In some villages, there may be dozens or even a hundred such homes, built in most cases by partnerships between farang men and Isan women. 3 Bars, cafés, and restaurants in Isan market towns cater to a clientele of middle-aged and elderly farang men. Far off to the south, in the entertainment districts of Bangkok and the beach resorts of Pattaya and Phuket, middleaged farang men...
