This comes up a lot, the retraction issue.
In the shower (or bath) gently pull your foreskin back to the point where it just begins to hurt, and stop. Do this a few times, do not force it. It will take some time (months!), be patient.
If it does not get better, or the tightness interferes with either erection or urination, tell your folks ASAP.
The next time your at the docs, tell him and let him take a look.
