Every relationship is different, and now a study has offered an explanation for why some couples are having more sex than others. As published in the Journal of Research in Personality, researchers revealed that it often comes down to certain personality traits.
Researchers examined 278 heterosexual newlywed couples for the study, during which the subjects kept diaries to measure how often they were having sex. They were also asked to take a personality test revolving around their extraversion, openness to experience, agreeableness, conscientiousness, and neuroticism.
On average, all couples reported having sex 3-4 days over a period of two weeks, and the project confirmed that men initiated sex more often than women. They also found that a couple was more likely to have sex if a woman rated higher on the agreeableness or openness to experience trait.
The couples also had to rank their satisfaction out of seven points, and if the man was more open, the couple was seen to be less satisfied. The opposite was true when the woman ranked high for openness, and both genders were less likely to enjoy having sex if their neuroticism levels were higher.
It's worth pointing out, however, that the study focuses on newlywed couples only. Who knows if things might look different for long-term, unmarried couples, or those who have been married for years?
Psychologist Andrea L. Meltzer told NY Mag: "What I can say is that, in a number of studies of newlywed couples (most of whom are extremely happy), couples report having sex approximately every three to four days. I am not sure, however, how frequently 'happy' couples who have been married longer (or even dating couples) have sex."
