If that goes against your core then it's wrong for you. It will cause nothing but internal strife. The question is then, what do you do when such a large obstacle remains? Do you, as the woman gets older, contain your libido (strong internal strife) or release it? Biologically, men are reproducers throughout their entire life. Many many have fully functioning testosterone levels until they die. Does this mean they should deny themselves simply because a woman's biology quits functioning? Do they come to some form of agreement with their spouse to meet their own needs? Pretty heady questions and go beyond single pair mating. My personal thinking is that one reason that men die younger than women is that this strife causes them to dwindle and the lack of biological purpose causes them to feel, subconciously, as not needed. After all, a women can get all her needs met at an older age without sex but men are still mostly functional. Should it not rather be that women need to be more active in ensuring that their sexually functioning male is kept at peace internally by selflessly providing a function that they no longer need? After all, since they don't "need" sex it shouldn't cause much internal strife to provide it for their mate .
