There is nothing to be ashamed off.
You have done nothing to make this condition happen. It is not a unique problem and many men do have a tight foreskin.
The problem is corrected when a boy is fairly young and has problems with urination.
Like bobdylan958 suggests make an appointment to see your doctor. He will refer you to the correct specialist if this is needed.
Best wishes.
Hi why not get to see your Family Doctor over this he would be your best answer, in the mean time keep stretching it ,a lot can be achieved , Take care ,
