Balanitis is an infection that can make you uncomfortable in one of the most sensitive areas -- the end of your penis and the loose flap of skin that covers the tip. It can be treated, and it’s often easy to prevent with some TLC. You can get balanitis at any age. If you're circumcised, you’re not likely to get it.
