“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,” says lead study author and psychological scientist Andrea Meltzer.
Looking at data from over 200 newlyweds, researchers found that following sex, couples were far happier in the two days following.
Couples were told to write in the diary whether or not they had sex, how satisfied they were with their sex life at that moment and how content they were with their partner.
According the report, couples who showed strong levels of the post-sex afterglow, said they were more satisfied with their marriage.
“This research is important because it joins other research suggesting that sex function to keep couples pair bonded,” Melzer adds.
