Ligation does not affect coitus, and neither female nor male ligation is performed at the expense of coitus. Except for the first month after the surgery, when the body has not yet recovered, coitus is not affected when the body recovers normally. Ligation surgery is performed to ensure normal coitus but not to prevent pregnancy, so it usually does not affect coitus. Female ligation surgery mainly involves amputation of the fallopian tubes at the isthmus of the fallopian tubes, so that sperm and egg cannot form a fertilized egg, and can achieve a reliable form of contraception. Therefore, the amputation of the fallopian tubes does not affect the lower genital tract, such as the vagina and cervix, and therefore does not have any effect on coitus. Other forms of contraception may not be needed after ligation, and instead intercourse may be able to be more unaffected without fear of pregnancy. So the purpose of ligation surgery is to provide contraception to avoid pregnancy after intercourse, but it does not affect the process of intercourse. So you can have normal intercourse after ligation and you can do so without worrying about pregnancy.
