Oh sure... I have flashed him "my magic" many times before, always in a playful, not-expecting-anything way. (Somewhere along the line, we decided that my vag was magical. In a joking way, of course. Since then, it's always been called "my magic.") Sometimes he smiles and grabs me. Sometimes he pretends I didn't do it and keeps going about his serious business (whatever it may be at the time).
I read on one of these posts or in one of the books (it's all swirling together right now because I've had trouble sleeping the past 3 nights), no matter how he reacts or doesn't react, he's taking it in. That counts for everything you put out, good and bad. So, I'll keep on smiling and flashing and having fun.
