I also believe that men are not honest about their true motivations. We want to have sex. But, sex, for a woman, can be incredibly complicated. And men, don't really consider the longer-term consequences, whereas women, I think, measure longer-term consequences. Women, I have read, are much more likely to choose men, whom they will stay with in marriage, for example, who they have chosen, because they have considered the practical aspects of the men's personality, etc, vs. more superficial considerations by men, which do not support deeper relationships that keep marriages working over time and through difficulty.
