Hello, You are experiencing vaginal bleeding during masturbation. It commonly occurs if you are rough with yourself and scratch your hymen or when you tear it. You will commonly have blood in your fingers when you put it in the vagina meaning you have lost your virginity. You have been using sex toys to pleasure yourself, sometimes scratching inside the vagina or cervix may be due to intense vibrations or rough usage. It may cause bleeding per vagina. Using sex toys in the vagina without making sure that they are clean, sterilized and infection free may cause vaginal infections, vaginitis, etc. It may cause inflammation of the vaginal wall and thus swelling, irritation, abnormal discharge, bleeding and itchiness. You can apply ointment Soframycin on the cuts, tears or abrasions, maintain good hygiene. Keep your private area clean. Wear soft cotton skirts and do not indulge in sex or any sexual activity or self pleasuring for a couple of days. Let it heal. If the symptoms remain persistent you can get clinically examined by a Gynae, you may need to get STD tests done, you will be treated accordingly. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Nupur K., General & Family Physician
