My earring wont come out (read decsription plz)?

Well, I have absoulutley no clue as to what the black stuff could possibly be, but the reason your earings won't go in is because for the first 3 months you are supposed to have your earings in at all times. That is what my person said. I forgot one day and the same happened to me. The black stuff may be from dirt in your ear or possibly just dirt that ran into it during your showers. You should turn your earings ever two hours or so so the hole will not close up. Good luck
