Honestly, as a pre-cougar but definitely not in my 20's, I don't have much of an attraction to younger men. If anything, I'd totally want to hook up with a handsome 40 something before a 20 something. It just makes me feel older to check out younger men. Take Taylor Lautner (Jacob from Twilight) - very handsome, fit, muscles...all that, and yes I did a count down till he actually turned 18, but really, that's kinda icky. Just makes me feel older than what I really am. If I were single now, at 36, I wouldn't date anyone younger than 30. I just couldn't do it.
I'm glad you touched on this Roz...because as someone in your age bracket (I'm 36) I can honestly say the exact opposite. I think it's probably because my father is 16 years older then my my mother but the reason I'd be inclined to go after a younger man is mostly because they are more open to change. (Here's where I go into generalities...fair or not fair, my opinion) Men tend to be pretty simple people anyway. (Eat, sleep, work, sex...play some video games...repeat) As they get older they often are more apt (then women) to be set in their ways...uncomfortable with change. Younger men are open to new ideas, are excited by trying new things. As I say, a generality, but it is my perception. In the meantime what are most women up to? Every woman I know is involved in an unusual 'project'. Whether it be in the arts, or going back to school, or travelling...women don't stop in their 20s from going after these sorts of things...regardless of the deep sighs and rolls of eyes they are probably getting from their husbands. When a man suddenly decides to have an unusual project...people call it a mid-life crisis. Why? Because it is uncommon for a man to adjust his lifestyle to something new and exciting. This is not always true of course...but there is a reason why men in comedies are portrayed as sitting on couches and watching tv with a beer while their wives are portrayed as going out doing various things. (See All in the Family...Married with Children...The Simpsons)
So I guess my point is, at 30-something a woman is looking for something new and exciting...enter 20-something hunky guy who is just starting out and has all sorts of fantastic ideas of what his future is going to be but no idea on how to get there. Hi2u project!
And that is not even touching on the very real fact that women reach their peak in their mid 30s and men in their late teens. And this I know from very personal experience. A 17 year old male and a 35 year old male has a very different libido...inspite of which brain they think with. There is thinking and there is DOING.
