I have trouble making sense of the exchanges between Sarissa and Harry early in CD when she admits that Mab is making her available as a sexual partner for Harry if virginity is required to be a Lady. Yes, Harry says there'd be an element of coercion involved in any sex they had since Mab put them in this position (as she is also trying to do with Harry and Lara at the end of BG). Also, Mab is clearly trying to establish an emotional bond between Harry and Sarissa. If that bond is established and they're sexually active then at some point one would have to imagine her Free Will would override Mab's putting them together. Unless Cat Sith would have appeared at that most delicate moment and figuratively poured ice water over the pair.
I didn't think that the Ladies had to remain celibate. I just thought they could not perform any acts that might result in pregnancy.

Unless Mab was counting on Harry's Dresdensity, that by having Sarissa tell him that she was there to be available that Harry would ensure she stayed virginal. That seems Mab somehow.
