I am 74 and what might be called "postsexual." And my wife, by her own admission, has never had much of a libido. When I used to get sexually aroused, she regarded it as rather comic and would indulge me like a lamb for sacrifice. Now I get sexually aroused by her now and then, but can no longer perform, so I simply ignore my hormones until they die down of their own accord. After a 36 year marriage, we are both fine with leaving sex in the past. I could go get some viagra, but really, what's the point? Sex, while enjoyable when young and useful for making babies (if you wish) is really not all that important in a relationship. As Andy Warhol once put it, after a certain age, "sex is nostalgia for sex."
