I am just wondering if maybe it is staying to moist under the fore skin so it wrinkles like you hands do when you keep them in water too long. I know that they say you should keep it really dry under the fore skin to avoid infections.
Have you been circumsizeed?
They are on the head, I'm 24, they are constant, I'm monogomous, and they cover the entire head.
Can you offer more information? Are they constant or do they fluctuate? Age? Monogomous? Areas of penis where the wrinkles form? Size of wrinkles?
See a plastic surgeon and get a penis lift.
