Symptom #2 Having unprotected sex.

HIV does not have symptoms. But having bareback sex (without a condom) is a clear symptom that you could get HIV. If you regularly do it without a condom, it's a question of how long until you catch HIV. Consider that one in ten gay men live with HIV, so sooner or later you will have sex with someone HIV-positive. Moreover, precisely those people who believe they'll never be infected with HIV never get tested and, in turn, have a higher probability of being infected and not knowing it.
