Bleeding after masturbating?

Britney

I bleed really hard after I orgasm, but this only happens when I stimulate my clit. There's no penetration, and it's very light, I keep my panties on and gently use a vibrator from the outside of my panties. No matter what, when I cum, blood pours like a murder scene. I don't understand what is wrong? Should I see a doctor? It's very rare for me to not bleed after orgasm, and it's always very heavy.
