It varies, different places have different practices, but it can often include removing the clitoris and some even sew the entrance to the vagina up (to be opened up later for her husband). The former is done to reduce female desire/pleasure so she won’t be unfaithful and the latter is done to ensure her virginity for her husband. it can be done on infants but is often performed on children or preteens. it can cause a lot of dangerous and painful effects.
