It is recommended that condoms be used for effective protection when engaging in unsafe sexual practices. This can largely reduce the risk of being infected with HIV or other sexually transmitted diseases, but it is not a 100% guarantee against the possibility of infection. Because in the entire process of sexual contact, condoms may break or even fall off. Once this happens, there is a risk of infection, but not after the risk, the consequences of using condoms and not using condoms are the same, because the process of using condoms can largely reduce, or even avoid contact with vaginal secretions or semen, thus reducing the possibility of being infected. But fundamentally, you should be clean in life, try to reduce the occurrence of unsafe sex, do not have promiscuous sex, from the root to do a good job of protection, in order to better play the possibility of infection to reduce.
