How long can you have sex with a tear after a side cut?

Natural childbirth does not necessarily do side cut, fetal weight is relatively small, fetal head is not large, perineal elasticity is better, generally do not need side cut. If the fetal head is large or too low, perineal elasticity is poor, most need side cut, side cut after recovery is better, about a month and a half, lochia completely discharged can be the same room.
