" 2) The relationships were casual and purely physical; no harm done.
WTF. I know that you've been taking a lot of heat lately for your other posts, but you had to know that that post would get you a male bashing.
Purely physical/casual relationships are only great for men and do cause harm to the woman. Yes woman can be stupid and sleep w/ sleezy men b/c they're drunk, in which case that is no sexual conquest but a jackpot. However, if you are referring to sober-sex, you are very mistaken. 99.99% of women want a committed relationship. Women will sleep w/ you on a friends w/ benefits scheme but only b/c they are secretly hoping that it will turn into something more. Bottomline: Casual sex is never a good idea if you actually care about the other person's emotions.
Nice to know that 57.2% of statistics are still made up. Your view of gender relations seems to me a very skewed one; assuming that only men have sexual appetites while only women care about relationships undergirds most of the problems of inequality to which you allude. A sexually liberated woman can learn to enjoy physical relationships just as much as the stereotypical man should. In any case, the focus is on pleasure. When I have sex with a woman, we have a very honest communication about what we find mutually pleasurable. This exchange of pleasure certainly constitutes an emotional component, but not as "baggage" that might otherwise weigh down the interaction unnecessarily. The key, of course, is to find a like-minded partner (and they do exist--usually a woman with some aesthetic sensibilities can understand the sharing of pleasure without any other involvement). I would describe the life philosophy as hedonistic, but it might give the wrong impression to those who don't know Greek.
