Iwantitnow - Ihmurria's post gives you all the information you probably need. It is hard to tell how old you are, but I would judge you are in your teens. You may have two things - 1) a "naturally circumcised" penis, with a short foreskin which covers only part of the head when your penis is soft, and thus circumcision was regarded as unnecessary, or 2) you had a very "loose" circumcision with only the tip cut off, like I did, so that much of the foreskin remains, but sits loosely behind or at the back of the head. Give us more information.
