For one thing, women seem to age a lot better than they used to. At least, I don't remember many of my mother's (and grandmother's) friends looking as good as a lot of women I see in the 40-65 age bracket nowadays. But it is not just looks - experience and even what some people would call flaws are very attractive. Not just sexually, but of course that is what we are really talking about here, yes?
Over the years, my definition of a perfect-looking woman has evolved from whatever the standard was for "perfect-looking" when I was twenty to now, where a woman comfortable with herself and her age and looks, who took the trouble to not just let herself go but carries some of the natural effects of aging with aplomb, is just incredibly alluring to me.
I don't think I care as much about the "tricks" HH is over there in the corner winking about. Those are nice, but by the time it gets to that, if it does (and it doesn't have to, of course,), you've already been through the lead-up to it, which is really the fun part. I do strongly agree with HH about how nice it is to not have to go through a lot of mind games; which I remember as being a common thing with younger women.
Of course, if like me you've been married awhile, you go through this stuff with your spouse, who you may remember as a firm young thing when you met her, but that was two kids and twenty years of living with you ago. . . These days, I tell the old lady she looks better to me now, at 40-something, than she did when she was 22. She thinks I am crazy, or lying to get sex, and I am not above that sort of thing. . . but in this case I really mean it. Providence has fucked with my mind, so that my wife with some mileage on her looks better to me than any twenty-something-year-old hottie does. And praise Allah for that. Keeps me out of trouble, and the home is generally a pretty happy place, most times. If that sort of thing happens to you, consider yourself a fucking lucky man.
