I am 68 years old, about 10 years ago I stopped passing semen when I climaxed.. the word implode came to mind. in contrast to explode ( when masturbating ) or in my loves "dream hole"... nada,
Old Truck (me ) seem to have gone full circle.. From the pre-puberty years. when discovering masturbation I would climax , to the tickles, or a good feeling in my loin, but no semen would come out, the first time it did it scared me sh*tless. ( but thats another story ) my question is: It this condition commond? or could it be due to my old age, multi Illneses, ie. diabetes, high blood pressure, what causes' the factory to shut down? should I see a doctor? what ?

Please Advice
