A study of newlywed couples, published in Psychological Science, a journal of the Association for Psychological Science, indicates that partners experience a sexual ‘afterglow’ that lasts for up to two days, and this afterglow is linked with relationship quality over the long term.
“Our research shows that sexual satisfaction remains elevated 48 hours after sex,” says psychological scientist Andrea Meltzer (Florida State University), lead author on the study. “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.”
… sex on a given day was linked with lingering sexual satisfaction over time. Having sex on a given day was linked with sexual satisfaction that same day, which was linked with sexual satisfaction the next day and even two days later. In other words, participants continued to report elevated sexual satisfaction 48 hours after a single act of sex. Importantly, this association did not differ according to participants’ gender or age, and it held even after sexual frequency, personality traits, length of relationship and other factors were taken into account.
