Oh and also...Silly...if I went out to the shop while my man was out there trying to use power tools on some important house project and I threw my arms around his waist and started rubbing my front against his back...he would stop me immediately and make it clear that this isn't an appropriate moment! But to a woman, when she is cooking or otherwise "working" at her house or children it is the same thing to her. You say both men and women do this, but I beg to differ. Men make it very clear very quickly what their personal space and physical boundaries are, and as a woman you are usually not welcome to come get into his space or on his body without his direct consent, especially if he is working on something.
I don't think it is as common for a woman to do this "getting your attention" or distracting you while you are doing something else as it is for a man. Not sure what others would say about this but, does your wife do this to you? Just trying to make you think about new things from the other side! It helps everyone when we learn.
