But the same percentage also said it was their biggest regret.
The second highest regret was snogging a work colleague, with 32%.
The new study also confirmed what many already know – it’s not easy finding Mr Right.
The women quizzed admitted to snogging 19 men before they finally found their soul mate.
The survey found 26% of ladies looked for love in pubs and 23% in nightclubs.
But it appears you needn’t try so hard as a third found love after a being introduced by friends.
An online survey was carried out with 2,000 women in the UK, aged between 18 and 60.
According to the research, 21 is the age when women kiss the most “frogs”.
More than half of the women surveyed (59%) said they were actually “repulsed” by one of their encounters – with 21% saying their date had bad breath.
Another 18% admitted to kissing a friend’s boyfriend, while 11% of women say they have smooched with their boss.
A total of 27% of those quizzed said they are still kissing the wrong man or have given up ever finding Mr Right.
But there is hope – as 73% of women said they had finally found “the one” .
Psychologist Donna Dawson said: “Kissing is a very powerful action and should be used carefully.
“Lips are integral to ‘mating rituals’ as they send sensory information to our brains, which in turn connects to our pleasure and arousal zones.
“The chemicals in our saliva also act to heighten the physical attraction between two people.
“All of this works to create a strong emotional bond between a kissing couple and gives them the illusion of instant compatibility, when this may not be the case in reality.
“Psychologists have maintained for years that the best way to meet an ideal partner is through a network of friends.
“Friends have your best interests at heart, and know what you are like and who you might be attracted to.
“Otherwise, meeting strangers in venues where the atmosphere is sexually-charged and alcohol-fuelled runs the risk of affecting your judgement about a potential partner’s compatibility and true intentions – and that includes kissing them!”
The survey was carried out by Smint, to launch its new pink Strawberry Mix for Breast Cancer Care.
A spokesperson said: “We love that the new research demonstrates that women are confident in their pursuit of love.”
The survey was conducted online by 3GEM research this month.
