20yr old male circumcision 6 weeks ago, 0.5 inch still open and not healing, what should i do? no pain - rest wound healed fine.

Leave it alone...: Based on what you described about your 0.5-in still healing incision, leaving it alone and continue the same care to keep it as clean and dry as possible. Most likely, this unhealed incision should seal in 1-2 weeks. If not as usually expected or worsening, seek timely evaluation. Best wish to health & incision healing.

Keep it clean: will heal in couple of wks and go and see surgeon for follow up.
