This pretty much explains it. If you have skin over the glans (head) of your penis, your uncircumcised. If you don't have any skin over your glans, you are circumcised.
The skin (foreskin) may be completely covering the head or may not. You may either be lightly circumcied, or your foreskin is just like that. Every penis is different.
If you're uncut, you can have your foreskin any way that feels comfortable. When using a condom, pull the foreskin back (same w/urinating)
