A while back I read about a study that found that when a woman is friendly toward a man she doesn't have sexual feelings toward, often the male will mistakenly believe that she does, and act on those feelings.
My response was, how is the male supposed to tell the difference? If there is a clear, observable behavior difference between how women behave when they are sexually attracted, and when they are just being friendly, then females should explain it to males when they get old enough to be interested.
On the other hand, if there is no observable difference, then females are just creating problems and should not be surprised if things go badly.
Women want to be respected as equals. That's fine, but in some ways respect has to be earned, and part of how you earn respect is by being open in the signals you send other people, instead of expecting them to read your mind, and then being upset when they fail to do this correctly.
