White fluid coming out of the vaginal opening after intercourse is usually a mixture of semen and vaginal secretions, which is a normal phenomenon. During sex, the mucous glands in the cervix, the vaginal wall and the glands of the endometrium will increase their secretions under sexual stimulation. When male semen enters the vagina, it liquefies into a more fluid fluid, and the mixture of the two may be discharged from the vaginal opening after intercourse. It is important to note that men and women who are not preparing for pregnancy should take good contraceptive measures and pay attention to the cleanliness of the vulva before and after sex in order to avoid infections. If a woman has abnormal leukorrhea after intercourse, she should go to the hospital in time for examination and targeted treatment under the guidance of the doctor to avoid delaying her condition.
