Researchers first surveyed 303 people and then, in a separate study, followed 121 couples for 21 days. That’s where expectations became more interesting than reality: in the daily data, how spontaneous or planned people considered a particular sexual encounter to be was not associated with greater sexual satisfaction. Belief in the superiority of spontaneity was more obvious than the actual advantage.
In 2025, the same research group went further with an experiment involving parents of young children. More than five hundred participants were assigned to different groups; one group was encouraged to reframe the idea of planned sex and intentionally make room for it. Two weeks later, that group reported more planned sex, a higher overall frequency of sex, and greater desire than the control group. But this is still one study in a specific population of parents, so it would be premature to turn the result into a prescription for every couple.
What interests me more is something else. We often evaluate a sexual experience before it has even happened: spontaneous feels authentic and passionate, planned feels artificial. That expectation itself becomes part of the experience.
Maybe the problem isn’t the calendar. Sometimes it’s the story we’ve already attached to it: “If we had to plan this, something must already be wrong with us.” The evidence doesn’t support that verdict.
