I have been in many situations where I'm with a woman (or multiple women) and we happen to either be walking together hand in hand, or arm around each other (usually when she's full of alcohol), or even on a bed at a party with a bunch of people at a hotel room. When is it appropriate to use touch, and when is it not appropriate? Are there any books/guides on the art of touch in the context of seduction or persuasion? I'm also blind, so I'd prefer not receiving advice on reading facial expressions and body language unless the body language is related to touch.
