Hello I share your concern This could be due to Phimosis in which condition foreskin fails to retract I would like further information to help you better like Your age and any history of unprotected sex? Is it since birth or recently developed? You can apply lignocaine ointment and you should try to retract it very slowly please don t leave it retracted you once you attempt to manipulate it by rolling over the glans, in the end please leave it over and in front of the glans. If you don t succeed than you may require circumcision. Hope this answers your question Best wishes
