He'll guide you by putting his arm on your elbow or in the small of your back (if he is interested)
The armguide isn't just good manners and a polite way of guiding you through a crowd; he's making sure he knows exactly where you're going by taking you there. He doesn't want to lose you! It also shows you're being "taken care of" so no other men need volunteer.
Along with the armguide, there'll be lots of accidentally-on-purpose touches.
