It is recommended not to have intercourse after the occurrence of contact bleeding because women who can have contact bleeding generally have problems such as columnar epithelial ectopia and fragile local mucosal tissue, and the mechanical contact brought about by intercourse can increase the risk of contact bleeding. Therefore, intercourse is not recommended until the diagnosis is confirmed, nor are behaviors that may lead to infection and inflammation, such as taking a tub bath or not changing underwear for a long period of time.
