As noted in one of the posts in the referenced thread, full separation varies from individual to individual for when it finally occurs. You can try pulling it back a very little at a time while bathing as the warm water will soften the skin. At sixteen it could take another year or two to separate on its own. I wouldn't be concerned nor worried at this point.
As for needing a circumcision, no. If the opening of the foreskin is tiny and does not easily stretch to go over the Glans as is sometimes the case when the foreskin extends out in front, then a doctor can give it a small nick as Brandye often mentions and this will give it the freedom needed. This is another matter from what you are talking about.
The natural "glue" that is bonding the Foreskin to the Glans will usually break down all on its own, however, if you want to help the process along, you can, by pulling against the bond a little at a time over the next many months. It is not something that you should just go for and rip. No...no.
