Tactile
Brooke was never a very tactile person. Self esteem low enough to cause (or be the product of; who really knew?) an eating disorder didn't do wonders for social confidence.
She wondered sometimes if those inhibitions were what kept her from being intimate with Josh for so long. She didn't mind kissing him, hell, making out was pretty darn nice some times. His body was certainly touchable, and when she did, she felt like she had bested herself, like she wasn't doing something wrong. She was normal.
It wasn't until Sam that she grasped the difference between "not feeling like she was doing something wrong" and "doing something right". So absolutely, consumingly right.
Because, inhibitions aside, Brooke was never a very innocent person.
