Ok so most of you will think im stupid but about a couple years ago I just didn't pull back my foreskin that often and it started closing up and I got scared and embarrised so I haven't told anyone for quite some time,, now its really closed theres only 10mm of not closed skin,,

Im scared, and embarrised more than ever,,, please someone help and tell me If there is any cream that will help it stretch, that I can get from a doctor, or is circumsision my only hope ????????
