What I really meant was that men set the expectations for other men, in the context of Chris' observation, that we expect the most of each other, which is why there are actually guys who prefer the company of women...because, if you can keep a woman in a good mood, and show her a good time, you can get away with anything; whereas men have real expectations of other men, and a man who doesn't pull his own weight can become PNG among other men PDQ.
On the other hand, in a sense, in a very literal sense, a man's sperm is his highest value to a woman. Thankfully, they don't yet set the standards for society.
