What Causes Irritated And Burning Vagina With Painful Urination?

FOR THE LAST COUPLE OF DAYS, MY VAGINA HAS BEEN VERY IRRITATED. WHEN I TAKE BATH, I'M ALWAY RUBBING IT. NOW I THINK I HAVE IRRITATED IT TOO MUCH BECAUSE I SEE LITTLE RED CUT. AND IT BURNS REALLY BAD WHEN I PEE. AND SEX IS VERY PAINFUL. WHAT IS WRONG WITH ME
