Charlotte (Kristin Davis) isn't exactly a nun, but she tries to stick to her Episcopalian values. And compared to her girlfriends -- especially Samantha (Kim Cattrall) -- she often comes across as a prude. The girls once shocked poor Charlotte by playing gay porn on their movie night. "You said we were watching an independent film!" she gasped. "I brought biscotti!" And though not a virgin, she decided to wait until marriage to sleep with first hubby Trey (Kyle MacLachlan). "So you're 'everything but' girl?" asked her best bud Carrie (Sarah Jessica Parker). "I like to think of it as 'kissing with extras,'" Charlotte replied.
