New York, Sep 6 (TIWN) An individual's premarital views about uncommitted sex, such as one-night stands or casual sex, may make it more difficult to remain blissfully married, suggests a new study.

Published in the journal Psychological Science, the research outlines several factors that can contribute to a marriage's long-term happiness or dissolution, including one big red flag: An individual's behaviour and attitude about uncommitted sexual relationships even before the marriage.  "Marital satisfaction generally declines over time, but what we've found is that when, prior to their marriage, one or both spouses hold generalised beliefs that uncommitted sex is OK, that can contribute to the failure of a marriage," said the study's first author Juliana French from Florida State University.  For the study, the research team collected and analysed data from 204 heterosexual, newly married couples.
