An in-depth study of 400,000 profiles has revealed the words women and men use to describe themselves on dating profiles that turn the other sex off.
But the results were not what singletons might have expected.
Just one per cent of female daters (compared to two per cent of male daters) want a retiring date.
A predictable piece of feedback from the hundreds of thousands of men asked about their preferences is that most of them are looking for a sexy woman - and one who knows it.
Another shock revelation was that 'curvy' is a turn on for men.
The adjective was the eighth most attractive word for women to dub themselves.
But, perhaps surprisingly, women were even more likely than men to be turned off by a shy evening at the movies.
Conversely, just 0.3 per cent of men were attracted to women who boasted about being happy.
And it is not just men who apparently want to be able to make their partner content, rather than finding someone who is already feeling good about life - just 0.4 per cent of women were turned on by the idea of a happy man.
Calling yourself 'shy' - and even 'happy' could be turning off potential mates while describing yourself as 'curvy', if you're a woman, is more likely to lead to a dinner date.
Unsurprisingly, it turns out both genders are looking for confidence in their other halves - so whether you're using an app or a website, shouting about your self worth is likely to work.Instead they look for men who prize their honesty - 13 per cent of those surveyed said it would be the most important trait in a potential boyfriend.
