Depends on what you mean by "older"... as everyone else is saying.
It's still pretty typical for men to go for women 5-10 yrs younger, and women to go for men 5-10y older. I mean, mature people 35-55.
Similar even in high school... most girls date guys their age or 1-2 yrs older, most boys date girls their age or 1-2 yrs younger.
Its so common I wonder if it might be something instinctive.
In adulthood I've dated women who were two-three years older than me sometimes, and some that were quite a bit younger. I lost interest in really young gals (early-mid 20s) not too long ago, after a girl half my age made a play... I gave it a try, it crashed and burned in a couple months. Had to put early-30s as a lower limit after that... got to have some depth and experience or it gets boring quick.
Now there are women my age or a bit older who are appealing too, some who are still sexy yes. Part of it though is that as an older man you realize you're looking for more than just a hot bod and a pretty face; you're looking for character, depth, experience, and so on.
But I'm not gonna lie... in terms of pure physical hotness, women are typically most sexy around 22-32yo and yeah it typically fades a bit as you get older than that. Young/healthy/fit and so on is lovely to look upon... but I have a saying: The young gals are just for looking at, you don't want to have to actually keep one. All surface and no substance, more often than not.
Helen Mirren, for instance (was in RED 2010 w/ Bruce Willis/etc) is in her late sixties and still quite a sexy woman, though in a different way from, say Nina Dobrev or Ellen Page or Zooey wasserface. Helen Mirram's appeal is slightly more subtle and less defined by sheer physicality.
So in essence its complicated. :mrgreen:
