Almost all of the 250 MSM surveyed knew that HIV/AIDS could be contracted through sexual intercourse and 80 percent cited condoms as a way to prevent the disease, although actual use does not reflect knowledge. Many respondents reported having experienced STI-related symptoms. For example, 42 percent had had burning or penile discharge and 22 percent reported having had lesions or pustules on their anus (Table 2). When asked about the causes of penile discharge or burning, most respondents mentioned such non-viral or bacterial causes as poor hygiene, irritation from intercourse without sufficient lubrication, spicy foods, long periods of abstinence, masturbation, too much sex, or other illnesses. More than a third said they had no idea of.
