It's forward, he wouldn't do that if he wasn't attracted to you. Now if it was his hand on your shoulder or upper back he probably didn't mean anything by it, but lower back or your waist is more sexual. If you have a problem with it don't let him do that. Remember, it's your body and no one has a right to touch you in a way that makes you feel uncomfortable!
