an itchy could be a yeast infection, and should be treated. or many people don't realize it could be AN ALLERGIC REACTION TO LATEX!!!! MOST CONDOMS USED ARE LATEX! It took me years to figure this one out. And some spermicides may cause itching like Nonoxidyl 9 Spermicide. BUT DO NOT STOP USING CONDOMS!!! There are LATEX FREE (just read the box, usually says so on front) or read ingredients and try to find without nonoxidyl 9.... but remember, without spremicide you may have to be more careful.
If you find that you think you are allergic to LATEX, you may want to let your dentist know too, since the gloves they wear are latex, and may cause similar brunging and itchiung around your mouth and lips.
hope that helps....
but I AM NOT A DOCTOR, AND YOU MAY STILL HAVE TO SEE ONE!
AN OUNCE OF PREVENTION IS WORTH A POUND OF CURE!!!!
