There are particular gestures women make that men don't. That head on the shoulder one is absolutely a classic. Another example would be that when a woman is in a man's arms she will often reach up to stroke his face, just gently running her fingers down the side of his cheek and around his mouth. A guy's hands are much more likely to be all over her ass!
That's not to say she won't run her hands up the front of his trousers, just to feel what's in store for her down there, but that only happens if she's pretty confident and wants to make it clear she's expecting this to go all the way. Otherwise, most of the gestures are gentler, more passive and even (apologies for being un-PC, but sex is the ultimate un-PC activity) submissive.
It all comes from the fact that she is likely to be smaller and weaker than him ... and that in the right context, with the right man, whom she desires, that helplessness - which can be terrifying or infuriating in other circumstances - suddenly becomes incredibly sexy. But at the same time, things like the facial touching are ways of establishing a kind of ownership of her man and - both physically and emotionally - drawing him closer to her. (That finds its echo later in a relationship when she adjusts his tie or his jacket collar, or brushes some lint off his chest: simultaneously caring for him, presenting him at his best and also possessing him).
Also, women are much more vocal, not just talking, but all the little sighs, moaons, 'mmm's, and so on. With your new voice, Jenny, you should be great at that!
