Just adding in my 2 cents.
In my opinion and experience, guys do get sexier to women with age. Of course, there's a tipping point when the age is too old and starts to slide back down to unattractive, but I'm not sure when this tipping point is, maybe close to 60. I think it's because:
1.) People stereotype age to equal experience. So they think the man is more experienced (in the bedroom, with relationships, with life, etc.), so she thinks that he can satisfy her needs better. Of course, I do not believe age = experience, but that is the stereotype and is probably true 60% or so of the time (more than 50%).
2.) Women see younger men as party animals and confused/indecisive about life (e.g., what job will I do?) and unstable. This can hurt the older man and put him as a provider, but it's usually more of a pro (especially if the older man can get quick sex and make the girl think that without sex he'll just move on to the next younger woman, and then she's the one trying to tie him down to a relationship and change him).
3.) The older man has set more into his own personal style and is confident. The men that I see
that continue to improve and progress themselves as they age have the best wardrobe/style and ooze confidence without saying a word (and without being cocky).
0.) This is 0, just as an aside, but some women do have a daddy complex; it's not just fiction.
When you're young, you think all of the older men get the women.
When you're old, you think all of the younger men get the women.
P.S., Nova, that picture is hilarious, and I want that Asian girl, dayum, damn, damn.....
