Hi,
Welcome to HCM,
If you can not avert your fore skin of penis ans is very tight then you are having
Phimosis and requires
Circumcision operation.
Many a time due to collection of
smegma skin become adhere to
glans and it becomes difficult to avert the fore skin.So if there is smrgma collection then try to clean the part gently and remove smegma.
Consult surgeon and get examined and do according to his advice.
Ok and bye.
