NEW YORK —Why do most men prefer ladies with curvier bodies, especially sharp curvy hips? According to a study, modern man’s this preference has ancient evolutionary roots.
According to a research carried out by a team from the University of Texas (UT) at Austin and the UT – Arlington has found that for a mate, man preferred a woman with a “theoretically optimal angle of lumber curving,” a 45.5-degree bend from back to buttocks allowing ancestral women to better support, provide for, and carry out multiple pregnancies.
“The findings enable us to conclusively show that men prefer women who exhibit specific angles of spinal bend over buttock mass,” said study’s co-author Eric Russell from the UT – Arlington in a paper published in the journal Evolution and Human Behavior.
This investigation consisted of two studies. The first looked at vertebral wedging, an underlying spinal feature that can influence the actual curve in women’s lower backs.
Around 100 men rated the attractiveness of several manipulated images showing spinal curves ranging across the natural spectrum.
Men were most attracted to images of women displaying the hypothesized optimum of 45 degrees of lumbar curvature.
This adds growing body of evidence that beauty is not entirely arbitrary or “according to the viewer” as many in mainstream social sciences believed, but instead has a coherent adaptive logic, added psychology professor David Buss from the UT Austin.
“This spinal structure would have enabled pregnant women to adjust their weight over the hips,” the authors noted.
These women would have been more effective at foraging during pregnancy and less likely to suffer spinal injuries.
Thus, men who preferred these women would have had mates who were better able to provide for foetus and offspring, and who would have been the able to carry out multiple pregnancies without injury.
The second study addressed the topic of whether men prefer this angle because it reflects bigger buttocks, or whether it truly can be attributed to the angle in the spine itself.
Around 200 men were presented with groups of images of women with differing buttock size and vertebral wedging, but maintaining a 45.5-degree curve.
Men consistently preferred women whose spinal curvature was closer to optimum regardless of buttock size.Follow @gorkhapost
Men also suffer from post-sex sadness
Even men feel sad after having sex owing to several reasons, according to a recent study which found that men suffer from Postcoital Dysphoria (PCD) which results in sadness, tearfulness or irritability following sex.
“The study breaks down the results of an international anonymous online survey of 1,208 men from Australia, the USA, the UK, Russia, New Zealand, Germany and elsewhere,” said a researcher Joel Maczkowiack in the paper published by the international journal of Sex & Marital Therapy.
The study focused mostly on men in heterosexual relationships, and all of the sexual relationships were consensual.
Co-author Professor Robert Schweitzer said that comments from the men he surveyed included, “I feel empty, I feel unsatisfied, I don’t want to be touched, I want to be left alone.”
Of the 1,207 men surveyed for the study, 41 per cent had experienced PCD, and 20 per cent had experienced it in the previous four weeks.
“Forty-one percent of the participants reported experiencing PCD in their lifetime with 20 percent reporting they had experienced it in the previous four weeks. Up to four percent suffered from PCD on a regular basis,” he added.
“The first three phases of the human sexual response cycle — excitement, plateau, and orgasm — have been the focus of the majority of research to date,” said Schweitzer.
Researchers said that men who participated and who had experienced sadness following sex described experiences ranging from “I don’t want to be touched and want to be left alone” to feeling unsatisfied, “annoyed and very fidgety.
“Another described feeling ’emotionless and empty’ in contrast to the men who experienced the post-coital experience positively, and used descriptors such as a ‘feeling of well-being, satisfaction, contentment’ and closeness to their partner,” he added.
“The experience of the resolution phase remains a bit of a mystery and is therefore poorly understood. It is commonly believed that males and females experience a range of positive emotions including contentment and relaxation immediately following consensual sexual activity,” he added.
Previous studies on PCD experience found that a similar proportion of females had experienced PCD on a regular basis.
But the case with men is not well understood at the moment.
“We would speculate that the reasons are multifactorial, including both biological and psychological factors,” Schweitzer further pointed out.
Anecdotal evidence from clinical settings as well as personal accounts posted on online blogs suggested that PCD did occur amongst males and had the potential to interfere with couple interactions following sex.
