Geeez HD - I consider touch to be a relatively standard way of saying "I'm interested. Are you?" And I think in a trusting, respectful R it is a hot way to initiate. I would LOVE it - it has been a long time since H made this kind of approach. I guess if I were you I would have no idea how to approach Mrs. HD - if you ask then it is "bugging" her, if you touch it is personally violating. Good thing your interest is fairly low at the moment.
I'm experiencing a little consternation because my libido is ridiculously revvvved up today and I know that ML is absolutely off the menu. After all the kid activities, homework etc...H is looking forward to sleeping and will not look kindly on wifely wheedling.
