Think of it from the perspective of a biologist. Women's sexuality is different from men. Both are seeking the highest probability of creating successful offspring. Successful means that your offspring create offspring. However women can't force their desired mate to copulate. And a woman's orgasm is not required for successful impregnation. She needs to ensure a male orgasm, so her whole being is constructed around attracting and pleasing men, particularly strong and successful ones. Once a woman has children her entire personality changes from trying to get pregnant to raising the children. From these understandings much of women's behavior can be understood. The way a woman attracts a mate is to be an exhibitionist. Wearing enticing clothes, or whatever. Pleasing the men she wants to mate with and turning a cold shoulder to the unattractive. A woman will practice with other women or by herself. Taking topless pictures, playing dress up. Spending hours upon hours trying to make herself more attractive. As she gets older (early 20s) and still has no children she becomes increasingly desperate, flashing her tits and ass, becoming promiscuous, in a scramble to become pregnant. As she engages in more failed sexual activity she become more and more desperate and is literally driven insane. Historically the cut off was 30, after that she was a spinnster -- a failed woman. However the mothering instinct is still there, so as a failed woman this is often redirected towards animals, be they 4 legged or 2. The way you turn a good girl into a cat-lady whore is to keep her from becoming pregnant in her late teens early 20s. Even if she succeeds in her biological imperative and has children, her sexuality is still about attracting and pleasing her man. So if he wants to see tits that's something she's naturally inclined to do.
