I am a widower for the last 16 years. At this age, my sex drive is high and being a widower I have no option but to masturbate whenever aroused. However, of late my foreskin turns sore more so after masturbation. Normally, on erection foreskin retracts automatically but in my case, I have to retract the foreskin manually without pain. Presently, due to soreness of the foreskin, retracting manually is slightly painful. Though a diabetic person, sugar is under control with medication. Please suggest some medicines or ointment for an application. Thank you.
