There is also a risk of HIV infection from external ejaculation. Sexual contact is a very important mode of transmission of AIDS. Sexual contact mainly means that during sexual intercourse, HIV may enter the body through broken mucous membranes such as the vulva, thus leading to infection. Therefore, for AIDS patients, external ejaculation is not a way to avoid AIDS. Generally, condoms need to be worn and related precautions need to be taken, which can significantly reduce the chance of HIV infection. Of course, to prevent the spread of AIDS, the main thing is to be clean, to have a fixed sexual partner, and to go to a regular medical institution, and if you are an AIDS patient, you need to be treated in time, which can significantly reduce the risk of AIDS transmission.
