If your penis is intact you Will have skin all the way from it's base to the tip or a bit past the tip. if you have been circumcised the skin stops near the top exposing the glans at the end. However, the statement above is not necessarily true as there are some uncircumcised men with short foreskins that barely cover the glans leaving it partly or totally exposed. The surest way to tell whether the penis is circumcised or not is the presence of the circumcision scar.

Boys are not born as circumcised or not circumcised. Circumcision is a surgical procedure. As a minor, it is something that your parents would have to decide to have done. If you are not circumcised, it is because they did not choose to have the procedure done. This would in all likelihood mean that they are already quite aware. There is no need to explain to them. However, if you think that it is something that you want done, you would need to have that talk with the separately.

You need to stay off the road!
