Balanitis is most often caused by a yeast infection. Get a good quality yeast treatment cream and apply it twice daily to all parts of your foreskin and glans. In 3-4 days, you should show improvement, but continue applications for at least 10 days to two weeks. Within 3-4 days, begin stretching the opening. If you can get two fingers inside, pull the opening apart gently and hold. Do this for five minutes each time, four times per day. Do not use soap to wash any parts inside your foreskin. Soap destroys the balance of necessary bacteria to keep the area healthy. If you have any questions, ask.
