Men who reported frequent kissing and cuddling were three times as happy, on average, as those who had less snuggling with their wives or girlfriends.
Women, meanwhile, said that such shows of affection had very little impact on their happiness.
But men were more likely to say they were happy with their relationship while women were more likely to report being satisfied with the sex.
An online porn study, led by an Indian-origin neuroscientist, has unveiled a shocking new vision of human desires that overturn conventional thinking: plenty of straight women are into male-male porn and erotica.
Women tend to use kissing to create a bond with their partners, and to assess them as potential mates. Meanwhile, men use kissing as a means to an end," said Susan Hughes, a psychologist at Albright College in Pennsylvania, USA.
While women usually consider a bad kiss to be a deal-breaker, men reported that they would more than likely still have sex with a woman even if she were a bad kisser.
Psychologists hypothesize that males "perceive a greater wetness or salivary exchange during kissing as an index of the female's sexual arousal/receptivity, similar to the act of sexual intercourse," wrote Hughes.
Is he hitched? I want him!
A scientific study has found evidence that women like to target men who are already in relationships.
Researchers at Oklahoma State University in the US use the term 'mate poaching' to describe this phenomenon.
During the study, they showed a picture of a moderately attractive man or woman to participants.
Half of the participants were told that the prospective mate was single, while the rest were told that they were not.
Researchers Dr Melissa Burkley and Jessica Parker observed that 90 per cent of the women participants were interested in a man when told that he was in a relationship, compared to 59 per cent when told the same man was single.
The results showed that only single women were more interested in pursuing an attached target rather than a single target.
No strings attached, here's the money!
Gigolos, who cater exclusively to women and used to be considered a sort of urban legend, has now become mainstream as more women are willing to pay for sex in no-strings-attached situations.
According to some women, they like paying for what they called the "perfect boyfriend experience", because at the end of the night, they pay the guy to go away.
Cheesy chat up lines
The next time you approach a girl, do not hesitate to try out a cheesy chat-up line because girls absolutely love it, for they give a glimpse of a man's sense of humour.
According to a study, six out of 10 ladies are more likely to fall for a man if he breaks the ice with a light-hearted one-liner.
Conducted by a poll website, the survey, which questioned 4,000 adults, revealed that four out of 10 women were still dating or were married to a man who first approached them with a funny quip.
However, not every line can do the trick for you-it was found that there are do's and don'ts in the dating game as well.
Lines such as "Do you believe in love at first sight, or should I walk by again?", and "Apart from being beautiful, what do you do for a living?" worked "most of the time".
But "Do you have a map? Because I keep getting lost in your eyes" and "Is there a rainbow, because you''re the treasure I''ve been searching for," were likely to end up in red-faced failure for being "too over the top".
