Because homosexuals are less aware of safety precautions during sexual intercourse, they tend to have more same-sex partners, and gay sex is usually anal, which greatly increases the risk of contracting the virus. Not all homosexuals are susceptible to AIDS, but the incidence of AIDS in the homosexual population is higher than in other populations, and as long as they have sex with HIV-infected people, they will be infected with AIDS, especially in the male homosexual population, if they do not have adequate awareness of safety precautions during homosexual sex, or even have more than one partner at the same time, which will increase the rate of infection of the AIDS virus. Moreover, many male homosexuals usually have anal sex, and the mucous membrane of the rectum is relatively fragile, which is easy to cause damage to the mucous membrane and rupture and bleeding during sexual intercourse, in which case HIV will be transmitted through the blood, thus increasing the rate of HIV infection. Therefore, homosexuals should do a good job in the process of sexual intercourse and safety protection, such as the use of condoms throughout the whole process, to avoid having more than one same-sex partner at the same time, and to maintain a normal and regular sex life.
