Though I'd say that the, the before part is actually kind of impressive. So often there seems to be a tempo that starts up that makes it very hard to break off for a shower when one's already engaged in a certain level of play. Unless you just mean showering before going on a date if at all possible.
That they're impressed by the after part is more depressing. Like finding out that one is the only male-type person that one's circle of female friends knows or has slept with that actually will go down on a woman.
