blister like marks on penis

Im 16 and I guess you could say I masturbate alot at least twice a day everyday for an hour or more.  I have noticed that under the head on the side of my penis is really reddened and on the head is a small red spot..not really a blister because its not raised...ive been putting antibiotic ointment on it and didnt masturbate for a week..but its still there. I am still a virgin, so I dont think its an STD. Ive been looking online for information and one site said it could be lichens planus. That didnt sound so good because it said it cant be cured. I dont want to have this on my penis forever especially since I havent had sex yet and it looks like a disease. Could it just be from masturbating too much? It doesnt really hurt or anything. It sometimes feels a little raw but not all the time. Please help!

Hello,
From the symptoms it sounds like rash due to friction rub and irritated hair follicle. Wash the areas several times with fresh water. Do not use any cosmetic products at the sites. You can apply some calamine lotion at the rash as it will help in soothing the skin. Also wear cotton undergarments. Application of mild corticosteroid cream and oral antiinflammatories like ibuprofen/acetaminophen are also helpful. If the symptoms are severe then it will be best to consult a dermatologist
I hope it helps. Take care and please do keep me posted in case you have any additional doubts. Kind regards.
