Yes, I did realize that. (Although note that I didn't say you are a dick, I said you were coming across as a dick. These aren't the same thing.) Two issues guided that word choice: First, it was an attempt (possibly a poor one) to speak in a language closer to the sort you were using so the point might come across better. Second, in this particular context, the relevant point is that in a highly male environment you were using a negative term for the genitalia of the other gender. That said, neither of these were probably very good arguments. While one could potentially argue that in our society "dick" is more gender neutral as an negative term than "pussy", that argument seems to be more of a rationalization than a genuinely useful argument. I suspect that there may have also been some degree of priming occurring given that I had earlier today had a conversation with a female homo sapiens who expressed disinterest in Less Wrong because it "looked like a sausage-fest" (and also apparently that this thread as well as some of the other relationship related threads were "creepy"). Some amount of Phil Plait's speech was also floating around. But even that is an explanation more than a good reason. So I'll just say that I was aware of what I was doing, made a conscious decision to do so, but in retrospect had poor reasons for doing it.

Rule 1 was incomplete. Judgments that things are of equal value are obviously suspect as well.
