Ah, yes, I remember when I thought my ideal type was tall, thin, and dark. Definitely dark. Blonds were not my thing.
Then, I started dating a short, stocky, blond. On the third date it hit me, "This guy is HOT! As in, scrabble right now, hot."
Unfortunately, the sedate gathering we were attending was not really conducive to that. However, if I'd blown him off because he wasn't "the type I'm attracted to," I would never have realized it.
