About the length. My wife, for months and months, acted like I was juuuust about done with length. This was from about eight inches on up. Finally, at 10.5 she was serious. Very serious. But for at least two inches of growth, she let it keep coming. Funny.
Hell, now that she knows, you have a lot more options. Keep going till she gets it where she wants it. Tie a ribbon around it for Xmas.
