SG-1 never let her "be a woman" as it were. She was (almost) always in uniform and acting all military and correct. I bet if she'd had a chance to do some wild and sexy movie roles when she was young, she'd have knocked our socks off.
I could count 3 times out of the show 10 seasons where she let loose
-When everyone turned to cave people
-In season 8 she had a fling with that cop Pete.
-When Felger dreamed Carter and Vala had a cat fight.
