question: I am 55, and have had infrequent sex for the past ten years. My wife is staying away to take care of kids' education, and my job is 1200 km away. So we meet hardly for a week or a fortnight -- twice a year. We enjoy sex. That apart, I do not hve sex. So is attrition taking its toll. Moreover, my nutrition level has gone down. I do not get erection at all. Now we are staying together. Please advise on how to get a stiff erectgion that lasts some time. lifestyle changes, food changes. I am total vegetarian. Thanks.
