Please see a good surgeon close to you for proper advise. This is not a major problem.
If you have been having this since childhood, you are most likely to have a condition called as 'Phimosis'. The skin covering the glans penis does not go back and if the opening is very tight, the skin bulges out while the person passes urine with a thin stream or in some cases by drops.
Normally the skin over the glans can be retracted or pulled back.What many doctors advise is, while having a shower or bath, to try and gently pull back slowly each time, over a period of few weeks, some find that the skin starts to come back. This would NOT be possible if the foreskin is very tight.
What you mean by light surgery would be that the doctor would have stretched the opening in the skin(to allow urine to come out more easily) or made a surgical cut under local anesthesia to widen the opening.
Now, if you cannot pull back the skin and you have pain while having intercourse or when the penis is erect or have problems in keeping the glans clean you can consider circumcision.
Circumcision is a surgical procedure, wherein the surgeons cut off the foreskin to allow the glans to be exposed. Once the wound heals, there would not be problems with normal life. This is done under general or local anesthesia by many surgeons or urologists, you can choose this option.
Some individuals are against removing the foreskin for personal reasons, in these patients, the surgeons can perform a procedure called as a dorsal slit. The foreskin is cut open by a straight cut from the hole where the urine comes up to where the glans ends. This will expose the glans but the skin is not removed. You can seek professional advise and go ahead. In case you are a diabetic, then it would be better to go ahead with a circumcision as he would prevent recurrent infections of the foreskin ( referred to as chronic balanoposthitis)
