Butts have been all around pop culture for decades. One thing they are for a fact, though, is interesting. You may not immediately think that the butt is the biggest muscle in our body, but when you break it down, it totally makes sense. After all, butt muscles do help move your hips and thighs while helping to keep your torso upright.
This includes having fuller lips, bigger penises in males , more prominent breasts in females and scattered tufts of pubic hair to signal all the bits we should be looking at. But why is it that some male humans zoom in further on that sexual obsession, becoming fixated on specific, isolated female body parts? The Boob Man Although the media has focused increasingly on butts in recent years, boob men are still the largest group of body-part worshippers. Mammary glands in human females have evolved to be far more prominent than in other primate species. This development, Burriss suggests, was caused by thousands of generations of men preferring more noticeable breasts. The Leg Man As to why some men are into legs, the psychologists are pretty much stumped. Well-toned calves emphasized by a high heel are a winner in my eyes. But is there anything that these three distinct breeds have in common?

Sexualization of the buttocks , especially of the female gender, has occurred throughout history. Sexologist Alfred Kinsey suggested that the buttocks is the primary sexual presentation site in primates. Some anthropologists and sociobiologists believe that breast fetishism derives from the breasts' similarity to buttocks, but instead provide sexual attraction from the front of the body. In humans, females generally have more round and voluptuous buttocks, caused by estrogen that encourages the body to store fat in the buttocks, hips, and thighs. Testosterone discourages fat storage in these areas. The buttocks in human females thus contain more adipose tissue than in males, especially after puberty. Evolutionary psychologists suggest that rounded buttocks may have evolved as a desirable trait because they provide a visual indication of the woman's youth and fertility. They signal the presence of estrogen and the presence of sufficient fat stores for pregnancy and lactation. Additionally, the buttocks give an indication of the shape and size of the pelvis , which impacts reproductive capability. Since development and pronunciation of the buttocks begins at menarche and declines with age, full buttocks are also a symbol of youth.
Evolutionary psychologists have long argued that many of the physical features heterosexual men are drawn to in women reflect traits that signify female health and fertility status. The basic argument is that our male ancestors developed an attraction to these traits because it enhanced their odds of reproductive success. These mating preferences are thought to have been passed down across generations and still influence what men are attracted to today on some primal level. Different spine curvature makes female rear ends look different in profile. It also impacts fertility. They argue that women who have a very straight spinal column are at a reproductive disadvantage because, when pregnant, their center of mass shifts forward in a way that puts a lot of pressure on their muscles and lower back, thereby increasing pain and risk of injury. In contrast, women with curving of the lower i.
