Whether or not the man washes his vulva after sex does not affect the chances of a normal pregnancy. However, if intercourse takes place during a woman’s ovulation period and the man man manages to ejaculate in the woman’s vagina without using any safety measures, it is likely to result in pregnancy. If you have intercourse during a woman’s safe period, you are less likely to get pregnant. Therefore, if you have no plans to prepare for pregnancy or have children for the time being, it is recommended to take effective contraceptive measures during intercourse, preferably by choosing condoms, which are safe and have no side effects. If you forget to take measures during intercourse, women can choose to take the emergency contraceptive pill afterwards to prevent pregnancy.
