The Art of Ushering

... and no I am not taking about working at a movie theater, but the concept is similar.
The most delicate and alluring part of a woman's body is the small of her back; as it curves ever so gently into the waist and back out again accommodating (one hopes) her gluteus maximus. It is the part of a woman that invites the eye for admiration and (naughty) sometimes the hand. One of the kindest actions that can show a woman that you "have her back" or that you support her is the gentle placement of a hand on the small of her back.
The skill lies in it being an automatic action, not one of superiority or governance of her movements. Barely touching her back with the relaxed palm of your hand, can give a woman the reassurance that you are focused on her. A women loves to feel that she is the only thing you are aware of. That her presence there with you is of the utmost importance. Even if secretly your head is somewhere else. Do not push into her, for that would be on the edge of rudeness, instead allow it to hover there so if she leaned back or hesitated in moving forward she would feel it.
A woman likes to feel that a man is strong and protective even if she doesn't need protecting. You never want to cross the line of insinuating that she is fragile and needs your help. However, she may through small actions be comforted in the knowledge that IF needed you are there.
What are the appropriate situations you ask? Leading her into a place is one, lets say you are walking down the lane and heading into a restaurant, or some other establishment, if you open the door for her; it would be followed with the gentle presence, whether you actually touch her or not, of your hand at the small of her back. The next appropriate maneuver would be if she is climbing up steps, a situation that she that might require some support. So utterly simple?! A small gesture like this makes a huge impression towards the affections of a woman in your life. This is one of those things that she will remember about you. One of the best things it does, is it allows you to frame her, saying she is with you, in your care- without possessiveness.
