I'm shooting from the hip here, but I would consider what you hope to gain from physical touching of your WW right now. Slight touch is generally discussed as a way to rebuild intamicy between too people committed to the MR without rushing it.
If she responds positively to your touch then what? If she doesn't break it off with OM, do you then become OM yourself? I think men could be coerced back through physical intamicy, but I don't see a light touch winning over a woman, I think they need to be emotionally stimulated for PT to mean anything. And Sandi2 always says a WW can only be emotionally attached to one man at a time.
