Ive had a red mark on my penis for about 3 weeks now.  It looks almost like a burn but there is no pain or itching.  It gets aggrevated when I have sex.  When Im not having sex for a few days it pretty much goes away.  There are no blisters, bumps, etc, just a rash.  Any suggestions
Hi, It can be Atlantis. It can happen during unprotected sex due to change in PH, infections or allergy. Try having sex with a condom. If the issue persists we can go for a swab test. If no infection then you can apply local steroids. Hope I have answered your query. Let me know if I can assist you further.
