This paper describes the accounts that homosexually active men give of their HIV seroconversion and interrogates these accounts for risk discourses. In particular, this paper asks whether the risk discourses of HIV researchers and educators are present in the men's narratives of their own seroconversion. Such discourses make reference to 'unsafe' sex--particularly the practice of unprotected anal intercourse, numbers of sexual partners or 'promiscuity', and the disinhibiting effect of drugs and alcohol. The data are drawn from an ongoing case-series study of seroconversion in which men who had seroconverted were asked to give an account of the occasion on which they believe they were infected. A number of themes were identified in the men's accounts. The men's descriptions of what they believe to be the seroconversion event indicate that their attributions, i.e., the reasons they give for their HIV infection, vary depending on the context. Within regular relationships, breakdown of negotiated safety, love and intimacy, and fatalism were among the explanations given. Seroconversion attributed to casual sexual encounters was more likely to be explained in terms of pleasure, lack of control, and with reference to particular sexual settings. The ways in which men understood their HIV infection were informed both by the risk discourse of HIV researchers and also by the discourses of love and pleasure, as well as that of control.
