its a little more painful to get circumcised at an older age but normal. You will get an erections a lot during this time and maybe painful. Also being circumcised doesnt make your penis larger, it may look larger but doesn't actually change things. Your penis will be the same size erected as it was before you had gotten your circumcision done
thanks a lot for your help
The doctor can give you salt peter to stop your erections while you're healing. I read it takes about 4 weeks for an adult to heal, so it's probably too soon to tell what is what at this point.
