Thank you for asking. I can understand the distress you are through. Your problem is suggestive of a condition called Phemosis. Due to tight foreskin opening, a complete retraction of foreskin is not possible. One usually faces difficulty in intercourse, and chances of frequent penis skin infection are also high if not treated timely.
Next Steps
Kindly show yourself to a general surgeon. With proper examination and assessment he can decide further course of management. Usually the definitive treatment is a surgical correction of the foreskin. It is easy procedure.
Health Tips
Don't worry. You ll be normal soon.
