The subject of "Sexual Encounters" is sexual fantasy, particularly male homoerotic fantasy found in the literature and art of South Sea exploration, colonization, and settlement. Working at the boundaries of a number of disciplines such as queer theory, anthropology, postcolonial studies, and history, Wallace engages in subversive readings of 18th- and 19th-century Pacific voyage journals (Cook in Hawaii and a Russian expedition to the Marquesas), an argument concerning Gauguin's treatment of female figures, and a discussion of homosexuality and Samoan male-to-female transgenderism. These phenomena, Wallace asserts, demonstrate the continuity and dissonance between Western and Pacific sexual categories. She reconstructs Pacific history through the inevitable entanglement of metropolitan and indigenous sexual regimes and ultimately argues for the importance of the Pacific in defining modern sexual categories.
