For a year I've beenusing  awater jet to masturbate, and it was fine for a long while; I could still get it off with my fingers, rubbing my clit, and get amazing orgasms, but something happened last week. I don't know what happened but ever since that water jet session, my clitoris has become numb. Only the center area gets any sort of pleasure and even then it wasn't as intense. I can barely get anything from my fingers. Moreover, the sides of my clitoris appear to be brown now, but the center is still somewhat pink, a bit darker I'm worried I might have done and killed the tissue, or perhaps got an infection, and I might have gangerene developing! There is no pain, there is no puss either. It's been two weeks since I last used the water jet (though I did use it just now, very lightly, to test the sensation)

So in short; The sides of my clitoris are numb EVEN to the water jet, only the center appears to be responding, albeit poorly. There appears to be discoloration; now a brown-ish in hue. Will I get my sensitivity and the color back if I leave it be? Or did I perhaps permanently damage (or even killed) my clitoris? I'm fifteen years of age.

Any insight would be appreciated; I'm very, very scared I will never get any pleasure from my clit ever again. In the case it does need to be mputated, or if it is permanently damaged, can I still get as much pleasure elsewhere? I've never touched my vagina after all.

Thank you.
