To Rappa:
No, you're absolutely right. Age does not indeed make someone magically better in bed. The thing is, normally, an older woman dating a younger guy is generally indicative of said woman having a powerful sex drive, and dating the younger guy because she thinks he can keep up.
As said from the woman I am currently dating, "Wow, I guess a younger guy is better, normally the older dudes have one shot and they are done"
Not to be totally over-explicit, but I'm exemplifying the natural involvement here. Normally older women don't want a younger dude mainly because of the drama factor. Younger people are more dramatic, usually. However, in that rare circumstance said woman finds a pretty relaxed dude, anything can happen.
So in the end, really, I say that because the older woman is dating you by her devices, not by yours. A woman who is older than a young man who is timid in the sack probably wouldn't even glance in his direction, because she either wouldn't care, or wouldn't know any better.
But yeah, you're right for the most part.
