I Have Significantly Reduced Sensation In My Vaginal And Clitoris.

I have significantly reduced sensation in my vaginal and clitoris. I had a boyfriend that was not very good in bed and I used "toys" to compensate, instead of cheating. I also used ribbed condoms to try and help our intimacy problems. We are no longer together. I think I have over stimulated my clitoris. When I try to masterbate, using only fingers, I have little to no sensation and I am sore afterwards. Is there anything I can do besides abstinence?
