I hate to be the one to spew the most obvious cliché, but there is far too much emphasis placed on the orgasm. "Able to come more than once, able to come at least this many times in such-and-such a time period..." Please people!
I tend to rapidly lose interest and tire easily after I orgasm. The faster I orgasm, the more quickly I lose "the zone". Sometimes this is a good thing, like if we have to go somewhere soon. Also, sometimes it's good if the guy ejaculates somewhat prior to the sex act, then he can focus on other things besides his impending orgasm.
Of course, these points have very little to do with whether or not someone wants sex in the first place.
