<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am 25 and recently after intercourse with my long term girl friend, my forskin becomes sore and irritated for up to 1-3 days, especially when my forskin is pulled back. It returns to normal after a few days but happens again after intercourse. Any idea what s happening?  <response>: Hello Thanks for writing to you may be suffering from a surgical condition called as fibrosis. You need proper clinical examination by a surgeon. You may need surgical removal of skin over glans penis called as circumcision. Circumcision is necessary because forceful retraction of skin may lead to a condition called as paraphimosis. Paraphimosis is an emergency because it compromises blood supply of glans penis. You should consult your surgeon. Get well soon. Take Care Chat Doctor.
