Phimosis is a condition where the foreskin on an uncircumcised penis will not retract. For children, this is normal. Effective retraction does not occur until a male becomes older, for most between the ages of 5 to 18. Scar tissue can form that interferes with movement of the foreskin. In these cases, stretching exercises may elevate the problem. If there is bleeding or pain, talk to your doctor before trying to retract the foreskin any farther.
Step into the shower. The exercise should be performed while showering to allow moisture to work as a lubricant.
Place your thumb and forefinger on each side of the penis after wetting it in the shower.
Slide the foreskin back gently. The goal is to move the foreskin back as far as possible without pain. Perform the exercise up to 10 times or more each time you take a shower. Full retraction may take time.
Repeat the exercise every day in the shower until the foreskin stretches enough to expose the glans at the end of the penis.
