Well, just because you're a certain way doesn't mean the entire population of older men is the same way. I'm different from most females in many respects: taller, lower interest in sex than average, no PMS, no perimenopausal symptoms, and good with maps/directions, to name just a few. That doesn't prove that all the statements made about women (on a population basis) are wrong.
I'd believe the Can't do it more than once part though. My BF is 46 & he's not springing back into action the same night, or sometimes even the next day. But he can go hold onto it for a long time, like you said. So I accept longer instances, over multiple instances.
Last time I had a guy ready to go for a round 2 right away, he was 23. And I took the second try because the first was too quick to happen, I couldn't get anywhere.
