<human>: About 10 days ago I had unprotected sex with a prostitute for the first time ever, after exactly 30 mins after I had sex , I saw this redness on between the head of my penis and shaft, its been there ever since, it usually turns white and starts peeling off in a way but when I take a shower its red again, I dont feel any pain, or itchiness in any way, I also did use a condom but the then didnt use one for about 3 mins.
<bot>: Thanks for asking in Chat Doctor forum In short: Mucosal erosion may have caused this. Explanation: Getting redness within 30 min of unprotected intercourse with anyone is not infection. As per my opinion it is the mucosal erosion for having sex without lubrication or having sex when both are Chat Doctor.  So, abstain from sexual activity for now and visit a doctor to get yourself examined for your lesion and for HIV/STD as you had unprotected sex with a prostitute.
