I have been masturbating a while now. I have never had the problem of bleeding. About 4 weeks ago, my boyfriend fingered me and I bled slightly. It was worrisome, but I assumed that I was cut by a nail. It happened again today when I was fingering myself and I bled again slightly 4 weeks later. It is only a little bit of blood and I don't continue bleeding after. I dont think it was a nail again causing the blood. I'm only 17 years old. I dont show any symptoms of yeast infections. I am also a virgin, so I don't have any STDs or STIs. Do you think that I am aggravating my cervix and causing it to bleed? Or is there something else that I should be worried about? Any solutions?
