I vary a bit. Multiple vaginal orgasms tend to get stronger and stronger with each one (but even the first is awesome, and I'd be satisfied with that if it was all I had on a given night), and I can keep going (or let my partner keep going) without breaking stride with vaginal orgasms.
Clitoral orgasms are a one-and-done deal, though, because my clit gets really sensitive afterward, but more than that, after a clitoral orgasm my body's just *done*. But each of those could be standalone--- maybe multiple vaginal one night, maybe just clitoral the next, maybe a long session with multiple vaginal, anal, and finish things off with a clitoral orgasm the next night. It all depends on how I and/or my partner feel.
