The whole point of females in the human species is reproduction. They're basically "nerfed" males who get the (essential) ability to bear a child in return from the nerfs.
Women have higher body fat, breasts, less muscles, significantly less upper body strength, wider hips (that's why men run faster, also the main reason for blacks mogging whites in running competitions), lower IQs, way less criativity and innovation capabilities on average, way less developed abstract intellect, etc.
All because their bodies are made to bear and birth a child and raise a small child. This is their purpose.
The smooth skin is to attract a male. Females are better looking on average than males. That's why women on women shit is universally hot and men on men shit is repulsive to most people.
Females have to look appealing to males, or else males won't get an erection and fuck them.
Males don't have to be that much appealing because they can just rape.
