Bleeding after masturbation is hymen tear?

Question
Hello doctor,
I am a female 18 years old this year. Since I was 13 years old, I have been masturbating. At first, I only felt from the outside of my vagina, but when I was 14 years old, I once urinated and found that the color of urine turned more bloody. I thought it was my first month, but I didn't get my period until I was 15 years old. When I was 17 years old, I tried to put my finger into the vagina about 3cm but I couldn't feel the hymen or not. So the doctor asked me if the bleeding after masturbation is the hymen tear? Ask your doctor for advice. I thank you doctor.

Hello,
To the question "Does bleeding after masturbation have to tear the hymen?", the doctor would like to answer as follows:
The hymen is a thin membrane covering the vaginal opening, located about 2cm from the vaginal opening. The hymen in each person has a different structure, some people have a very thin hymen, so it is easy to tear when exercising, but there are also people with good elasticity, so when having sex, it may not bleed. The hymen usually has one or more holes for the monthly menstrual blood to drain out. Most women are born with a hymen. However, there are a few cases where women are born without a hymen.
Females often masturbate by stimulating large lips, small lips and other sensitive points. Masturbation if you do it gently, only massage or stimulate the outside of the genitals and do not put anything into the vagina and do not go deep, it is possible that the hymen will not be torn. And if you masturbate too deeply, you can tear the hymen.
Not every hymen tear will bleed, so you may not feel pain or bleeding at that time. Therefore, to know exactly if the hymen is torn or not, you need to go to the doctor to determine if the hymen is torn or not.
The first child's case is that he should not put his finger into the vagina because it can be dangerous: hymen tear, vaginitis... To determine if he has torn or lost his hymen or not. If you still have questions about bleeding after masturbation, you can go to a hospital under Vinmec Health System for further examination and advice. Thank you for trusting and sending questions to Vinmec. I wish you a lot of health.
Best regards!
