Bleed every time I masturbate

Whenever I masturbate, using my fingers or a sex toy I always bleed... Its been persisting for several months now. I took a break from masturbating trying to see if I cut inside myself and let it recover... After I gave it time to heal, I tried again only to be met with blood. Am I being to rough? I’m so confused... Does anyone have advice on how to reduce it or what symptoms it could stand for? Any advice is welcomed. Thank you.

Tmi, but just finished masturbating and the blood just came flowing out, I am not on or near my period date currently
