An HIV positive diagnosis is given to a person who is infected with HIV or Human Immunodeficiency Virus. HIV is a terrible infection that often leads to AIDS.

HIV is common among gay or bisexual men. About 1 in 5 gay or bisexual men have HIV. Gay or bisexual men account for a large majority of HIV diagnoses as a whole, and over 80% of HIV diagnoses among males. In short, if you’re a gay man then you’re much more likely to get HIV.

Also, HIV positive gay men are almost 100 times more likely to get anal cancer than the general population. All of this is because gay or bisexual men often have anal sex with other men. Anal sex can cause anal fissures, which are basically cuts or tears to your anus which can get infected.
