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?
