The bigger the woman's thing is, the more enjoyable and comfortable it is.

Usually women make some moaning sounds when having sex. People understand the sound of moaning as a "natural" thing. It is a spontaneous physiological phenomenon. So, is it a sign that the louder she screams during intercourse, the more comfortable she is?

Researchers in the UK have found that expressing enjoyment is inextricably linked to increased feelings of pleasure. Researchers at the University of Leeds in the UK found that female friends are generally more accustomed to communicating their pleasure to their partners during sexual intercourse. They believe that being able to reach orgasm is the result of their partner's better performance and their efforts.

For men, the noisier their sexual partners are, the more they enjoy sex. The researchers investigated 71 women's performance during sex and found that they often made the most excited sounds before and after their male partners reached orgasm. More than two-thirds of the women admitted that they sometimes screamed unconsciously to help their male partners achieve the most exciting shot.

According to the study published in the Archives of Sexual Behavior: "More than 92% of the volunteers believed that moaning during sex could help their partners feel more aroused and more confident, and more than 87% said they often did so on purpose."

A website surveyed more than 1,000 volunteers and found that women now make louder noises than men during sex. More than 94% of women admit that they moan louder than men, while 70% of men believe that the woman under them makes louder noises.

Relevant experts explained that the reason why women are more excited and moan louder than men is because women's orgasms are more intense. The nerves around a woman's clitoris are thicker than those around a man's penis, so the pleasure and excitement during orgasm are stronger.

Sex expert Tracey Cox said women often feel pressured to moan louder when expressing pleasure. Because some theories or logics believe that since women are more comfortable than men during sex, they have an obligation to express themselves more, that is, to moan more. However, Ms Cox said the study did find that noisier sex often meant more enjoyable sex.

He added: "Although it's interesting that women tend to be loud and moan during sex, there's no scientific explanation for this. It's like when we go to a concert, some people jump up and down and make a lot of noise, while others are quiet throughout, but that doesn't mean the quiet people are unhappy or not enjoying the concert."
