It's a way of trying to make us feel inferior because they need to keep us down to make themselves feel superior. I expect those certain attitudes from men. It upsets me though when women carry those judgements or worse yet, when a woman is willing to get plastic surgery done on her body to try to live according to those beliefs. It makes me cringe. I feel sorry for women like that because they got to her and she believes she's not good enough without the big boobs and she's desperately afraid that a man won't love her without them.
I can't date someone younger than myself either but it has nothing to do with aging. It has more to do with maturity. I think men mature slower than women. A woman needs a man, not a boy.
