Thank you for your query,
Some time the prepuce of the penis becomes narrow producing a pin size hole which leads to difficulty in pee and called phimosis
This will lead to recurrent urine infections and kidney
problems during in long term if not treated.
Gradually because of scarring the hole closes and leads to obstruction of urine flow.
So consult your Pediatrician
as early as possible to examine the hole, to assess any local infection and for appropriate referral for intervention if required.
Hope I have answered your query.
