I was shaving my vagina about 5 or 6 days ago and must have caught the razor on one of the most sensitive areas of skin at the bottom near anus. 

I now have small tares where the skin has come off which is stinging and painful whenever I move.

Does anyone know how long this will last before it heels and if there is any cream or anything I can put on it to help the healing?

I'm in a lot of pain and very uncomfortable!
