Can persons 70 years old up still enjoy sexual intercourse? What can be done to an old man (70 up) who still longs for sex but can't because of erectile dysfunction? The patient in particular doesn't subscribe to outside aphrodisiac, medicines, cream, ointment, etc. that will be taken orally, applied, etc. What he prefers perhaps are foods and diet that will render in him natural and regular penis erection. Please help ASAP.
