Recently I Had Some Serious Chafing (almost Like Diaper Rash)

Recently I had some serious chafing (almost like diaper rash) on my penis. I used a solution called mms1. The solution is one part sodium chlorite to one part citric acid. When combined makes chlorine dioxide (Which has done wonders on scrapes and rashes on my skin before). I soaked my penis in the solution briefly then poured the rest on my penis Then let it air dry. I did this three times during the day. That evening I noticed a slight redness to the head of my penis. I then proceeded to put hydrocortisone on it. Later on into the evening the redness was worse and began burning. Almost like a sun burn. I have put aloe Vera as if it were a sun burn. Minor relief. I began getting small blood spots on the penis head. I now started using petroleum jelly. The burning is mild and comes and goes. It seems to help a bit but I guess not healing as quick as I would like. Any suggestions? Please help.
