I don't know about you, but I've detected a recurrent theme in some holiday gift advertising.
Many ads that I've seen and heard directed at men seem to point to some subtle sexual payoff from the recipient. Jewelry especially.
The most disturbing of these is a TV commercial showing couples seeming smooching under some mistletoe. In actuality, the man is holding a set of car keys above the woman's head, and it seems as though she is providing these meaningful kisses in return for the man handing her the keys.
I guess women have changed. If my wife has given me sex in return for a gift, I'm not aware of it. I've always had to work much harder for it (hahaha, that was a joke).
