MUST READ: Happy Wives have the most sex with their husbands

We've all heard the scary stories that, when you get married, there's a chance that sex might become a teeny weeny bit routine. Gone could be the days of afternoon delight and here to stay could be the days of Wednesdays and Saturdays only.

Obviously every marriage is different and your sex life can only be what you make it but, according to new research, there's one type of wife who gets it more than the rest.

A survey of 278 married couples, conducted by Florida State University, has found that wives who are happy, laid back and agreeable have more sex than wives who are not.

Interestingly, the husbands personality traits didn't affect the frequency of marital sex at all.

The couples were asked to keep a sex diary for two weeks alongside taking personality tests. They also had to rate their sexual encounters from one to seven.

On average, the couples had sex three or four times in 14 days but those with wives who were pretty chilled and not overly neurotic had it more. The level of neuroticism also played a part in the satisfaction as the husbands and wives who were perceived to be highly neurotic enjoyed sex less.

So, the study suggests that once we've tied the knot, us women can either chill out, let go of our stresses and doubts and have lots of enjoyable sex, or we can be a bit uptight and have less.

Nagging women, you have just been depriving your self of good sex which is part of the gift in marriage (legal sex with out season).
