I am 59 years old and has itching around the penis head for the past 6 months. consulted doctor and tested sugar level which is normal and also no infection detected. same thing happened some 10 years back and got rectified after a month. i am on the opinion that at that age i was having intercourse daily and due to the discharge of fluid during intercourse from my wife it got cured. now also i am having full sex desire but my wife was not able to co operate because of nil secreation of fluid in her vegina tried with external lub also and no secreation. her age is 53 years. can you suggest a good remedy.
