In the late 1980s Wilton came out as a lesbian, which gave her a strong sense of identity and politics as well as informing her intellectual work, although she never felt completely accepted by lesbians who had come out earlier in life because of her personal history of heterosexuality. She wrote in 1993, "the positionality of "lesbian" offers a potent site from which to investigate the social, cultural and political interlocution of gender and sexuality". She saw herself as having a distinctly lesbian perspective on the issues she researched in a way that challenged the assumptions of colleagues and gay men, particularly in relation to gendered behaviour. In the lesbian edition of Sexualities (3[2], May 2000), Wilton noted the marginalisation of lesbian issues within sexuality studies and the journal. This conflictual approach was contra-punctuated by a warms in her personal relationships, which embodied a strong sense of solidarity with co-workers on sexuality, especially with gay men. She was keen to rework the debates on the relationship between gender and sexuality, and sought to integrate them as a focus for interdisciplinary study that included health policy,
film theory, sociology of sexuality, as well as feminist and
queer theory. Wilton's writing was aimed at both academic and lay audiences. Her published material reflected theoretical work on sexuality aimed at academics, a book designed for practitioner training, an introductory text for policy makers, discussion about the
self-fashioning required by women who transition from heterosexuality to lesbianism, books for lay members of the communities involved in her research, and an edited volume on lesbians and film. ==Professorial and posthumous recognition==
