Thank you for your query,
The problem you are having is phimosis
In this problem, circumcision
to be done to overcome this condition.
Circumcision is a minor surgery and can be done under local anesthesia
without much pain.
If this problem is not corrected it may lead to sudden obstruction of urine when accidentally the skin goes back and stuck there.
So consult a general surgeon
and take his opinion.
Hope I have answered your query.
