6 days after my circumcision healing well, there's a yellow residue, looks like fat & won't wash off (as well as a tingling sensation). please advise?

Normal healing?: Congratulations on taking a very important, bold, and often difficult step to help prevent HIV, especially imporant in southern Africa. Good show! 6 days is much too soon for complete healing. If no fever, severe soreness, or spreading redness, it's probably just normal healing. Give it a few more days. If in doubt, return to the doctor or clinic where you were circumcised. Congratulations again!
