Sex may be key to a happy marriage, study finds
By Honor Whiteman
What is the recipe for a happy
marriage? According to a new study, sex is a key ingredient. Researchers have
found that sexual intercourse produces an "afterglow" that lasts for
2 days. What is more, this afterglow may boost long-term relationship
satisfaction.
Lead author Andrea Meltzer, of
Florida State University, and colleagues recently reported their findings in
the journal Psychological Science.
A number of studies have shown
that sex contributes to short-term bonding between partners, but the
researchers note that the majority of couples do not engage in sexual activity
every day.
According to the International
Society of Sexual Medicine, only 21 percent of married men and 24 percent of
married women have sex on 4 or more days each week.
So what bonds partners in
between sexual activity?
Meltzer and colleagues
speculated that sex produces an afterglow, or a period of sexual satisfaction,
that enhances partner bonding in the periods between sexual activity, and that
this boosts relationship satisfaction in the long term.
The researchers tested this
theory by analyzing the data of two studies, which included a total of 214
newlywed couples.
As part of the studies, the
couples were required to complete a daily diary for 14 days. Each day, spouses
were asked to report whether they had engaged in sexual activity with their
partner, as well as how satisfied they were with their sex life.
Couples were also asked to
rate their relationship satisfaction, marital satisfaction, and partner
satisfaction on a daily basis.
Additionally, the marital
satisfaction of each couple was analyzed at study baseline and 4-6 months later
at a follow-up assessment.
Stronger sexual afterglow
linked to greater marital satisfaction
During the 14-day study
period, couples reported having sex on an average of 4 days.
Not only was sexual activity
associated with same-day sexual satisfaction, but also the researchers found
that a single act of sex produced an afterglow that persisted for 2 days.
This finding remained after
accounting for a number of possible confounding factors, including age, gender,
sexual frequency, personality traits, and length of relationship.
On looking at martial
satisfaction, the researchers identified an overall decline between study
baseline and the follow-up assessment.
However, they found that
couples who reported a stronger sexual afterglow were more likely to report
greater marital satisfaction 4-6 months later, compared with couples with a
weaker sexual afterglow.
Meltzer says the study
findings are important, as they support previous research suggesting that sex
plays an important role in partner bonding.
"Our research shows that
sexual satisfaction remains elevated 48 hours after sex. And people with a
stronger sexual afterglow - that is, people who report a higher level of sexual
satisfaction 48 hours after sex - report higher levels of relationship
satisfaction several months later."
