A good roll in the hay shouldn’t take all day.

Being intimate for hours on end is a sex-ercise in futility, according to new data which claims sexually active sweethearts can achieve euphoria in less time than it takes to do a high-intensity workout.

“Americans and Britons who are sexually satisfied prefer sex to last around 35 minutes, including foreplay and afterplay,” say sexperts at ZipHealth, a virtual wellness hub.

Satisfaction from shaking the sheets is a vital aspect of most romantic relationships.

Specialists in Chinese medicine suggest couples — specifically honeys in their 20s — indulge in mind-blowing, eye-rolling sessions every four days in order to enhance their interpersonal connection, as well as their individual health.

Pros of the practice warn that “insufficient sex is considered a cause of disease.”

Scientists at Minnesota’s Walden University, too, revealed that women, from Zoomers to boomers, are at a 70 percent increased risk of death when they fail to get busy at least once a week.

So ZipHealth analysts, who surveyed 1,000 pleasure-seekers in the US and the UK across the generations, pinpointed the exact minutes each hanky-panky exploit should take, per romp, to ensure optimal outcomes.

“Typical duration of sexual activities among satisfied Americans and Britons,” read the study,” Foreplay: 15 minutes, Intercourse: 15 minutes and Afterplay: 5 minutes.”

However, couples who spend an extra five minutes on foreplay experience more female orgasms — a feat most Gen Z men struggle to help their ladies accomplish — than those who can’t eke out the excess effort, per the findings. Investigators say partners who watch porn multiple times a day are often able to tack on the additional few moments of boudoir bliss.

The researchers also determined that 36 percent of freaky folks in the US prefer having sex at night, and that an impressive 39 percent actually last the longest after dark.

The finding echo a recent global poll via luxe lingerie label Pour Moi, which found that 10:09 p.m. Saturday evenings is the most popular time to getting it popping.

“It’s really interesting to see how intimacy varies from person to person around the globe,” said the naughty know-it-alls. “But also to know that it is the weekend evenings that seem to be the most popular time for people to feel at their most relaxed and ready to enjoy time with their partner.”
