When I was young I forced my foreskin down before it was ready to detach. Now I have scar tissue where the foreskin detached. The scars don't bother me however just after i'm done ejaculating my foreskin gets really tight sometimes so tight my penis gets extremely small to the point where it looks like i've been outside in the cold. My penis is a little over average length and a decent amount greater than average but my penis gets a lot smaller when this happens.
