Thank you for your query at DoctorSpring.com
The symptoms you are experiencing are because of masturbation and use of hair conditioner as lubricant. The chemicals have caused local tissue damage.
You need to clean the area with water every day and not apply any soap or any chemical. You can apply any emollient for local relief. Don't masturbate for at least two weeks to allow the healing to happen.
Patient replied :
What emollient do you recommend?
You can apply Calamine lotion to soothe the irritated area as of now.
I will advise a petroleum based lubricant in the future to prevent this thing from happening again.
