Foreskins come in all lengths, just like penises. You do need to work at retracting that foreskin, for alot of reasons....one being cleaning under there on a regular basis. The other is that it will need to move some for sexual intercourse etc. It can be stretched so those things happen without pain. I'd suggest that you look around on this thread under foreskin topics, you'll find numerous posts about stretching and such. Keep in touch and we'll be more than glad to help, and don't worry...this is common for us uncut guys!
