Because it is sexy... ;)
Evolutionarily speaking, it is to attract potential mates. A large buttocks indicates fertility and that the female will be able to carry and bear young. This is why women developed wider hips and larger buttocks than men.
It's an evolutionary response. A sign of health among other things.
Men typically have narrow hips and less round buttocks. Women typically have wider hips and rounder, fuller (or thicker) buttocks.
For some reason in the last 20 years some young women and some older women seem to think a man's buttocks is sexy. Where this came from (from the attractiveness of a man's face to his upper chest and sliding Northwards) no one knows. No, if a woman looks at another man's buttocks it only means she is admiring him and doesn't mean she is having anything more to do with him.
Buttocks and thighs.
A female's pelvis is wider than a male's pelvis, especially if a woman has had a child. The male pelvis is narrower and remains narrower throughout life. Also note that some races have smaller buttocks while other races have larger buttocks. The only way to change buttocks that are narrower and flatter to get fuller, bigger, or plumper is if a person becomes obese or if they have filler injected (a surgical invasive procedure).
supposedly
The shape and size of an individual's buttocks are primarily determined by genetics, specifically the distribution of fat and muscle in that area. Some women may have a combination of genetics that predispose them to store fat in the buttocks in a way that is perceived as aesthetically pleasing. Additionally, regular exercise targeting the gluteal muscles can help enhance the appearance of the buttocks by increasing muscle tone and definition.
No there all kinds of buttox,
Biologically, women tend to have a higher percentage of body fat than men, which can lead to a larger bottom due to the distribution of fat in different areas of the body. Additionally, hormonal differences between men and women can also contribute to the differences in body shape.
Men's buttocks are typically flatter and narrower at the hips. Women's buttocks are typically wider at the hips. Many women's buttocks are also rounder and fuller. Both men and women have "saddle bags", which is extra fat on the sides between the waist and hips.
The appearance of cute buttocks can be achieved through a combination of factors such as regular exercise to develop muscle tone, maintaining a healthy body weight, and choosing clothing that enhances their shape. Additionally, good posture can also help highlight the buttocks in a flattering way.
