A couple other things that women ought to know about the male orgasm:
Yes, men usually come sooner. On the average, anyways. There are steps women can take to try and correct this -- request more foreplay, for starters. Switching positions may be the best solution, though. When a man is on top, he moves in such a way as to maximize his stimulation, but this usually minimizes the woman's. When the woman is on top, everything changes.
Men can have more than one orgasm. It's usually not as easy as for women, though, and we're a little jealous of this fact. But if the guy doesn't fall asleep right after his climax (or isn't allowed to), a woman can evantually coax a second orgasm out of him, and possibly several more for herself. The second orgasm is usually an order of magnitude better than the first one, because it's a lot more work to get it. (Women, I'm told, climax a little more easily with each successive orgasm. Men are the opposite.)
