Before you wanked Freud and impugned my virility, did you consider that perhaps you've never seen a woman have a real orgasm? I'm talking about the neurochemical response, not the merely impressive visual effect of flinging your custard a few feet.
With practice, women can train their bodies in ways we can scarcely understand.
Seriously, though. I mean, it's certainly possible to have two orgasms without a refractory period in between, but I don't think it's really a full climax, because you're not emptying both barrels, so to speak.
