Often as you get older your personal 'needs' change and/or your ability to satisfy someone else's needs no long exists or is no longer possible. This can happen to a man or a woman. Also I have seen people where the man, who is 15 years older than his wife is retired and the wife is still working and then later on when he is 70 and she is 55 she becomes practically a carer/nurse to him while still working, cooking and cleaning as he can no longer do this as he never kept himself fit. The woman invariably loses out. When I was on Vietnam Cupid I had a lot of young women showing interest in me who were 20 years younger than me! Some of them were incredibly attractive too. I used my head and had to turn down their advances nicely and I tried to point them in the right direction. Some men don't! This practice has been stopped in Cambodia in order to protect the young women.
