After Circumcision I still have the swollen part under the tip

It sounds like your Dr. was extra kind to you and left your frenulum in place instead of cutting it off. Its like a cord or a thin and stretched piece of penis skin starting from just below your penis's piss slit and going down your penis shaft a short distance to your circumcision cut mark on the penis shaft. This frenulum gives a lot of extremely fine and extra pleasurable sensations to a man during sex and masturbation since it is full of sexual nerves for helping men to enjoy sex more than if its cut off. Thank your Dr. for sparing this extra sensative male part of your healthy penis from the needless knife of circumcision. You'll enjoy sex way more with it in place and feeling all that great sex.

totally. because of this, I needed to go to the operating table again. It was nothing that horrible, at all. but my doctor told me that we should do this to prevent some other problems. it is not the only thing that someone can expect after this procedure. there are so many other things and some possible circumcision complications. after the surgery, the penis normally becomes swollen after and this thing about swelling is usually biggest between the line of the circumcision and the ridge of the head of the penis. Skin of your penis is different and this is something that you should not be worried about.
