Hi Emily, Your numbness and swelling could come from you not orgasing, your body builds up and thing swell up then if no ogasm, its not released, so when you do ogasm every thing goes back to its unarouse state.
But things just go back but slowly.
Any help
Good Luck
Try putting a cool cloth on yourself to see if you can get the swelling down. If that does'nt help then yes, see your Dr. How long has this been going on? I'm not sure about the numbness. It's most likely because of the swelling.
