Im still a virgin and during masturbation i've bled a lot, could this be to do with my hymen?

Here are some ...: Based on the sequence of events, vaginal bleeding is highly related with the acts of masturbation. To delve into what and how it happens, collect & bring the detailed info on the onset, degree, duration, resolution, etc. of such occurrence to Gyn-Doc for analysis + physical exams + tests as needed while the event is fresh. Of course, self-adjusting is possible but may take time with poor outcome.

Blood=opened tissue: Fresh blood is a sign you scratched or tore some tissue.What tissue is not clear, but it is likely from some area that you touched during your self-sex activity.Sometimes these will heal in a day or so if kept clean, but if you are filling pads you need to see a doc that can examine the area and see where the blood is coming from.
