I think that most males would enjoy beauty products, though. Even current trends in marketing point out that men also want to take care of their skin, among other things. If they had the option and weren't raised to think it was womanly (or gay), you can't convince me that most men would not buy and use more products. And I'm not stereotyping, because I also fully acknowledge that there are plenty of women who don't enjoy beauty products, either. I just know that current numbers are significantly skewed because of societal pressure. I also majored in cultural anthropology, so this is not something that I'll concede.
I don't believe in many inherent differences among males and females. Too much evidence points in this direction.
