Psychologists believe that when we were all living in much smaller communities or tribes and everyone knew everyone else, reputation naturally became everything. So, if you were known to be rejected by a person then your suitability rating was diminished. Equally, if you were accepted then your suitability rating increased. It's quite similar to how Google ranks web pages. A link from a quality web page improves your ranking while a link from a poor quality page reduces it. The danger of being visibly rejected is that it encourages others to reject you too. In this case it’s just another form of peer pressure. I.e. "If Jaya rejected abhinav maybe there's something wrong with him? Maybe I should reject him too just in case. Hell I don't want to be seen with Jaya's reject anyway."
If you think this system no longer applies then just watch how people behave at parties or nightclubs. Subconsciously, men will only approach a woman if they feel that they have more than an eighty percent chance of being accepted.
This is where flirting and sex signals become important. In a sense they are a code used between humans to test the levels of mutual attraction before visibly acting and thus risking rejection. Where people are watching and a rejection is taking place, the person doing the rejecting often exaggerates the act so that the spectators are in no doubt as to who is the loser. Sometimes seen as cruel this is actually a form of self protection. The person doing the rejection cannot afford the peer-group doubt that they themselves might have been rejected.
here is some body signal's which show interest of women into a men
The Hair Preen: Women with long hair often twirl or play with it out of habit but It's also a sign of nervous or playful arousal. It's used to attract a man's attention or to show him that his masculinity is attractive to her. This signal is sometimes confused with hair tugging which actually indicates the opposite - intense discomfort and a desire to be somewhere else. In this case the hair is "jerked" and forcibly pulled. When a woman preens her hair the motions are slower and luxurious. The hair is stroked and twirled in a sensual fashion. In real life a person would have to be blind to not notice the difference.
The Glamour Pose: Arching her back to emphasise her bottom and flexibility (youth), pushing her breasts forward and playing with her luxurious hair, the model to the right is exaggerating normally subtle signals into large movements and dramatic sexual gestures.
This is most often used by a woman where the male target is a fair distance away or where she wants absolutely no doubt about what is on her mind. Exaggerated body language is often seen at large gatherings or public spaces like a beach were simple "quieter" signals are often unnoticed.
The Lip Lick: As a body signal this is pure dynamite an one to which men often overreact Woman lick their lips for two reasons - they're either dry or she's sexually interested.
If a woman places her tongue at the corner of her mouth and then sensually licks her upper lip she consciously or subconsciously wants you to know she's getting very interested. It doesn't mean she wants the man to launch himself over the table and onto her but it does mean "don't be a dummy - even you can't miss this."
My Lovely Ass: The female bottom, both amongst primates and humans, holds a fierce attraction for males. Buttock augmentation is rapidly becoming common cosmetic surgery particularly in countries where a curvy bottom is considered a woman's sexiest attribute (Brazil for example).
This signal is done by placing one hand on the hip to pull the fabric taught across her cheeks and then half turning away so that the man can appreciate the shape and beauty of her bottom. One hand is often placed on her stomach to make it less obvious that she is also arching her back to make her bottom more prominent.
Dilated Pupils! When shown pictures of the same people that either had the pupils of their eyes airbrushed larger or smaller, almost all people tested indicated that they felt more attracted to the pictures with the larger pupils. Most importantly, they couldn’t explain why. The reason is that our pupils dilate when we’re feeling sexually aroused. Pupils also dilate when it's darker so perhaps that’s why candle light dinners are so romantic. English Tudors of the fifteenth century actually placed drops of deadly belladonna poison into their eyes to dilate their pupils and create the effect.
