Core Guide: There are 5 million to100000 gay men in China. According to figures released by the Ministry of Health at the end of last year, the HIV infection rate among men who have sex with men in China is about 1.35%. This figure is nearly twenty times higher than the infection rate of the general population. According to the survey, the probability that lesbians are infected with AIDS is very small. General infection is transmitted through blood, that is, rude behavior during sexual behavior, which leads to wound rupture, but this probability is too small. Why do gay men get AIDS more easily than lesbians? The high incidence of AIDS among gay men is caused by HIV (human immunodeficiency virus). HIV is transmitted through certain body fluids, such as blood, vaginal secretions, semen and milk. Because HIV is parasitic in these body fluids in high concentration, most people will be infected when they engage in the following activities: 1. Have unprotected sex (vaginal sex, anal sex or oral sex) with infected people. 2. Use drug needles, syringes (injecting drugs), tattoos or piercing needles for infected people. HIV must enter your blood to infect you. That is to say, if you have sex, the other person's blood, semen (including penis secretions) or vaginal secretions will enter your vagina, anus or mouth. Even if you can't see the virus, there is a risk of infection. The following behaviors will not be infected with HIV: kissing, hugging, touching, sneezing, coughing, exercising together, using tableware or bathtub. No cases of transmission through saliva, sweat or tears have been recorded. Mosquitoes, fleas and other insects will not spread HIV. Lesbians have a low probability of suffering from AIDS. The reason why gay men are at high risk of AIDS is that many gay men, under sexual impulse, do not pay attention to protective measures and directly touch each other's sexual organs or have anal sex, which are the fuse of AIDS. However, lesbians can't directly touch their sexual organs, and they need to use their fingers or massage sticks to assist, which greatly hinders the transmission of AIDS.
