I am an 18 year old female, and since the age of, 13 I've known how to masturbate. At first, I only attempted to stimulate myself via external touch, and without internal penetration. However, at around 14 years old, there was an incident when I was toileting; I observed that my urine had a bloody color. I used to think that was my first period, but in actuality my menstruation cycle did not start until I was 15 years old. When I turned 17, I tried to insert my finger into my vagina to feel for the hymen, but I couldn’t seem to find it. Hence, I want to have some counseling from the doctor. Do signs of bleeding after masturbation mean that the hymen has been torn?

During sexual intercourse, some women experience heavy vaginal bleeding, especially after their first time. Many women have this bleeding for several days. So what causes prolonged bleeding after the first time having sex?
