I am 27 and my husband is 51 quite a bit of age difference however age is just a number as long as they are of adult age of course. As far as him keeping up with me sexually easy to find ways around it. such as if the man is good at oral sex could make up for it. Also if it is a problem of not him keeping up with you but a prob of ED ways around that as well. Such as toys, strap-ons, viagra. Many many things could make up for it and for the men out their that have ED just because you have to use toys does not mean you can't be satisfied as well if your wife gives good oral.
