Last year, researchers found that on average, once a week was the ideal amount of sex for a couple to be having in order to maintain happiness in a relationship (studies also found that open relationships are NBD these days, so take from that what you will!). Yet with no one couple ever the same, there’s bound to be some duos that are exceeding this number and others that are falling below it.

If you’ve ever wondered why some couples hit the sheets harder than others, researchers at the University of Florida just may have your answer. According to their study, which analyzed 278 newlywed heterosexual couples, it may lie in a personality trait. A female one, in particular: openness to new experiences.

Participants in the study, who recorded sexual activity in a diary for researchers, were also asked to take a Big Five personality test. While the male’s personalities were found to have no bearing on the frequency of sexual encounters, the study showed the more open to experience or agreeableness that a woman was, the more frequently she and her partner were likely to be engaging in sex.

In short? Openness as a female personality trait was directly correlated to the frequency of intercourse each couple had.

It also played a role in the sexual satisfaction of the relationships —again, women were likely to see a positive correlation between their level of openness and their sexual satisfaction. Men with this same trait, interestingly enough, were found to have opposite, negatively correlated satisfaction levels.

Huh! While we can’t say for sure how much truth there is to this with regard to any one couple, it’s definitely a surprisingly interesting stat, no?

Do you believe that this personality trait affects how often a couple gets it on? Let us know over @BritandCo!
