Reported risk situations most commonly occurred longer than 15 days ago and in private locations with anonymous partners of unknown HIV serostatus. On average, men estimated their risk for HIV or STI infection as 3, measured on 10-point Likert scale (0 = Very low; 10 = Very high). 29% of men reported one or more symp- toms that may be associated with primary HIV infection (oral lesions or infection 11%; night sweat 10%; diar- rhoea 9%; fever 8%; muscle and joint pain 8%; vomiting 2%;).

To learn more about differences between groups of utilizers, two distinct subgroups were created: those with a history of both, prior tests for HIV and STI and those without a history of either test (table 4). Com- pared to men in the 'no test group', men in the 'test group' were significantly older, were more likely to self-identify as gay, and were less likely to live in a stable relationship. However, there were no differences between the groups in terms of the motivation for consultation or characteristics of prior risk situations. Page 5 of 9 (page number not for citation purposes)
