Why didn't the woman bleed the first time?

Patient's question:

No

Doctor's answer:

There are many reasons why a woman may not bleed during her first sexual experience. 1 Occupational factors, such as athletes and dancers, intense exercise may lead to the rupture of the hymen. 2 Disease factors, unmarried women with gynecological diseases undergoing pelvic examinations or surgeries, which may cause the rupture of the hymen. 3 Trauma to the external genitalia or poor masturbation habits causing injury. 4 The hymen has good elasticity and large pores, so sexual intercourse may not cause rupture or unsuccessful intercourse, so it cannot be determined whether there has been sexual activity in the past based on whether there is bleeding during the first time.
