Thanks for your query.Based on the facts that you have posted it appears that you have
removed some mass from ventral aspect of your penis 10 days back and wound has not healed completely.
This are of skin is potentially wet due to excessive sweating
and takes little more time to heal.
You have deep wound over penis It will heal up by secondary healing and will take at least 3 weeks for complete healing.
Please continue daily cleaning and dressing .You may take antibiotics to prevent infection.
