Homosexuality, mainly referring to men who have sex with men, has a greater chance of getting AIDS than heterosexual sex. First, because of same-sex behavior, many people do not use condoms because they do not have to worry about pregnancy, which increases the risk of infection. Second, among homosexuals, many are not exclusive sexual partners, have multiple sexual partners, and have a messy sex life, which greatly increases the risk of infection with the virus. Third, same-sex behavior generally uses anal sex, which can easily lead to anorectal mucosal rupture and bleeding, greatly increasing the risk of infection.
