Kirk was addressing a newbie officer who had been called in as a last minute replacement navigator on a high-priority, high-stakes mission. And she'd just taken a potential blow to her confidence by an abrupt change of commanding officer from the one she'd expected. (I just saw the scene again, only minutes ago, in the Director's cut.) I maintain that she made it about her celibacy oath, and given Deltan attitudes about sexuality, it was not likely to have been embarrassing to her. I did misremember the "Take Lt. Ilia in Hand" bit with Sulu as being in the Director's Cut; it's in the network TV cut (the 143-minute version; I checked my VHS tape), and Sulu's not leering: he's staring, and clearly overwhelmed. And the scene covers a lot of backstory.
I'm now watching the corridor scene with Decker and Ilia. I also misremembered how much backstory it covered.
And now, Ilia has anesthetized Chekov with her mind, with Chapel looking on.
I'd forgotten just how good the Director's Cut is. As I recall, even the music editing and the Foley were better than previous editions. Although I still clearly remember just how badly botched the theatrical cut was.
