I am 29 year old male and my foreskin doesn't retract. It is stuck to the skin bridge(glans). I have always had sex with a condom, hence did not have any problems so far but now I am going to get married and am worried how to retract my foreskin.. please advice

You need to see your doctor about this problem as it will have to be surgically taken care of. It is easily fixed. Not a big production. King Louis XVI had the same problem.
