Recent research has suggested that neurotic couples could benefit from spending more intimate time together.
Published in Social Psychological and Personality Science, the report found that neurotic newlyweds who engage in frequent sexual relations have a marital satisfaction that is equal to their less neurotic counterparts.
Michelle Russell and James McNulty from the University of Tennessee led the study.
They commented: "High levels of neuroticism are more strongly associated with bad marital outcomes than any other personality factor."
Following 72 newlywed couples over the first four years of marriage, the researchers found that couples were averaging sexual intercourse about once a week during the first six months of marriage, dropping to about three times a month by the fourth year of marriage.
While high levels of sexual activity were not found to be universally associated directly with a 'good marriage', the study did find that neurotic couples who reported higher levels of sexual activity also reported higher levels of marital satisfaction.
