What attracts younger men to mature women?

A mature female fan of mine writes:

"Maybe my beauty is the main reason I am approached so often - the guys find me attractive and sexy - I am not saying that is a universal experience for older women. There is no doubt that I am also approached because I am mature and intelligent (Many women, unfortunately, do not realize what a turnon these things are in a woman for a real man and end up getting too bogged down with their outfits or makeup or the layers of fat on the tummy or whatever other insecurities they have), and in a few cases because I have financial and other resources. A lonely horny young man would rather have the companionship of a good looking older woman than just an older woman, and I still have a body that gets looked at. I have found that stating up front that I do not engage in casual intimacy turns off only the "grosses" enquirers and likely attracts more than it outs off. I am first looking for relationship and honesty - then whatever follows. It seems most appreciate that."
