Five year old still has penis adhesion. it doesn't bug him but shouldn't he have grown out of it by now? how to fix?

Here are some...: Did he get circumcised at younger age? If not, his condition can be watched as long as the exposed part of glans penis is slowly getting bigger; give more time because the pace of natural process of separation between glans penis and foreskin may widely vary. If circumcised, post-circumcision adhesion may occur and prevent the natural separating and receding of foreskin. So, see Doc as needed.
