Quoting ♫ boobook ♫:" I think my sons foreskin reattached itself is that a problem? I was helping my 5 yr old in the shower ... [snip!] ... about? Please don't comment if you have no intact sons.. UNLESS they were intact but had to be circumcised for medical reasons."
OP here is some info for you : Foreskin was retracting now it is not? (From Dr. Paul Fliess
Sometimes a previously retractable foreskin will become resistant to retraction for reasons that are unrelated to impending puberty. In these cases, the opening of the foreskin may look chapped and sting when your son urinates. This is not an indication for surgery any more than chapped lips. This is just the foreskin doing its job. If the foreskin were not there, the glans and urinary opening would be chapped instead. Chapping is most often caused by overly chlorinated swimming pools, harsh soap, bubble baths, or a diet that is too high in sugar, all of which destroy the natural balance of skin bacteria and should be avoided if chapping occurs. The foreskin becomes resistant to retraction until a natural and healthy bacterial balance is reestablished.
You can aid healing by having your son apply a little barrier cream or some ointment to the opening of the foreskin. Acidophilus culture (which can be purchased from a health food store) can be taken internally and also applied to the foreskin several times a day to assist healing, and should be given any time a child is taking antibiotics.
