First, why? are you having prolems with retracting your foreskin, is this just for looks, the you need to think why are so msany men who been circomcised are now regrowing there foreskins, and yes it can be done, just have a look on altp***s .
Look if you just think this is the thing for me, then google the just pose the question, what is the down side of having a circumcision.
Good Luck
If you are serious about want to be circumcised, go ahead and have it done. I choose to have it done around your age and have absolutly no regrets..I should have had it done sooner.
Where do you live? I may be able to direct you to circ clinics in your area.
for some it is good and for some it is bad.healing will take about three months.if you think having the sensitive head/glans of your penis always exposed would be better for you then do it.but if having your penis glans rubbing on your clothing would seem painful to you then do not do it.if you are athletic or exercise/walk often it is probably better to stay uncircumcised.if you are sedentary it won't matter much.
