Are you mad for your fella to ditch the Spiderman bedspread, and stop finding his flatulence funnier than a Michael McIntyre DVD? Bad news lady, you could be waiting quite a while.

Men finally grow up at the age of 43 – a full eleven years after women ‘mature’, it has been revealed. A study into the differences in maturity between the genders reveals that eight out of ten women are convinced blokes remain immature well into their thirties and forties.

The research of 1,000 men and 1,000 women found respondents believe signs of male maturity begin to appear after the fortieth birthday, with 43 the average age given.

Eight out of ten women believe that men ‘never stop being childish’ – with breaking wind, burping, eating fast food in the early hours and playing video games their biggest bug-bears.

Staying silent during arguments, not being able to cook simple meals and re-telling the same old jokes and stories when with the lads were also hailed as signs of immaturity.

The research, commissioned by Nickelodeon, showed that both men and women agreed women reach proper maturity much earlier than guys, at the age of 32.

Men were nearly twice as likely to describe themselves as immature than women, with one in four men believing they are actively immature.

Women were also twice as likely as men to feel that they were the ‘grown up’ one in their current relationship.

One quarter of women felt they were the ones made all the important decisions in the relationship, with the same percentage wishing their partner would talk about themselves and what they’re feeling more often.

Women also found men’s biggest maturity failings included still finding breaking wind funny, driving too fast and playing video games.

Three in ten women have ended a relationship because they lost patience with the guy being too immature, while a whopping 46% of women have had a relationship in which they felt they had to mother their partner a bit too much.

In fact, on average, women have to tell their cheeky partner to ‘act his age’ more than once a month – an average of 14 times a year.

Immaturity does have its upside though, with four in ten people believing immaturity is important in a relationship because it ensures the partnership stays fun and keeps things fresh.

One in three people also think a bit of immaturity helps in bonding well with children.
