Brief Answer: as mentioned bellow Detailed Answer: HI. This is very true that the males can have an active sexual life till he really becomes frail and physically incapacitated. Please give answers to a few questions which are self explanatory:: ( I have read about good health in Medical history) Is he suffering from any disorder like Diabetes, backache, Prostate enlargement or so. Was / is he a smoker or takes alcohol? Is he open to discussions about sex with the spouse? Does this mean that at the start of sex the organ is hard and well erected but slumbers faster? Is there any problem in the family that worries him all the time like financials, family break-ups with children or relatives? Is he already taking some medicines foe whatever reasons? I am sorry to ask so many questions- but they will give us the reason for unsustainable hardness. The possible solutions: Get all the physical health related to the problems I have mentioned. If detected get them treated. If everything is normal, a XXXXXXX discussion with the spouse, Change of atmosphere, place, position all can help a lot. If needed you can try Viagra ( if no heart problems), This definitely helps a lot. Start with 25 mg and increase the dose if necessary.
