@Habu: oh no--she was definitely asleep. She's slept through earthquakes before, and through my younger sister bouncing on the bed. She could definitely sleep through some quiet, not so active sex. Which is the only reason we did it anyway.
Sex life is pretty good, actually. Since the IUD has only progesterone it doesn't damp down my libido as much as the combined BC pills. So now I'm horny, like, 95% of the time instead of 90%. Whoppeee. But the happy part of it is that it's summer, so teh bf isn't too busy.
