The two men and women who washed their private parts after making love generally still have the possibility of pregnancy, and can not avoid the occurrence of accidents. If a man has normal ejaculation, there is definitely a possibility of pregnancy, so if you are not planning to get pregnant in the near future, you must pay attention to good contraceptive measures during intercourse, such as wearing condoms or oral contraceptive pills, etc. The actual fact is that you can only reduce the chances of gynecological diseases by washing your vulva and play the role of cleaning, but it does not have any effect on contraception.
