For the past two weeks I have been retracting my foreskin in the shower every single day. Yesterday, as normal, I retracted my foreskin. This time instead of having to gently stretch the foreskin back over the head it would simply not stretch. Previously I had at least half a centimetre, so to speak 'spare' foreskin. Now it won't even cover 2/3 of the penis head. When the tip of the penis or in particular the 'whole' come into contact or rubs with anything (even my underwear) it causes an excruciating sharp pain. This isn't practical for my school life as it is difficult to readjust my penis without people noticing. Any suggestions on how to relieve the pain or how to help return my penis and foreskin to its previous state would be appreciated, thanks.
