Well my friend. There are things we need to know to help you find an answer. Things such as; Pain, rashes anywhere else, painful urination... pretty much everything thats abnormal for you down there. But the people over at webmd.com have a nice lil troubleshooting page and heres the direct link, I hope this assist you in possibly finding a cause, although the best and only for sure way to find out whats going on is to visit your doctor.
