What causes circular dry spot on foreskin of penis?
Patient: Hi I have a circular dry spot on the foreskin of my penis. With no pain, discharge, ulceration, and no tenderness. I Had unprotected sex with a relative stranger 6 months ago. Did all the std testing and everything came back clean, including follow up blood testing. However in Canada we have no blood test for herpes. Because of this I am quite concerned. Could it be from masturbation? I am quite regular at 2-3 times daily. Always dry masturbation as well. Doctor: Thanks for asking in healthcaremagic forumIN short: Dryness could have caused this.Explanation: If you are negative for all STDs then be happy. You need not go for testing herpes.  You would have got pain if it was.                     Masturbating whenever excited is not bad but should not become like habit(like 2-3 times a day). Try to divert your mind for some other activity. Good luck
