I mean no disrespect, but it's safe to assume you've never seen an actual shooting script. That said, Loken the actor is not being directed to touch every body- as unconciously or in the way she touches every body, as often as she does.
Don't get me wrong- i love watching her touch, and her sex scenes in l word are unbearably erotic (imagine what was edited:)). It's still inappropriate (from an acting/character standpoint) for Jane Vasco to be as tactual as Loken (unconciously) plays her.
