It's very hard to say with such little description but unprotected sex exposes you to the risk of STD's. Go to the doctor for an exam, ASAP.
i am not so concerned with the "burgandy colored clitoris" as i am with the vaginal pain. most of our vaginas are indeed a reddish color. you should not experience vaginal pain. you did not really give a good description in order for us to help. its difficult enough on line anyway but please post more if you'd like some help.
