Despite the long held theory that morning time is the right time for great sex, hormone expert Alisa Vitti says the real magic hour is actually 3 p.m., giving some scientific backup to the whole idea of afternoon delight.

Vitti told the Daily Mail that around 3 p.m., women have high levels of the hormone cortisol, which makes you more energetic and alert. Around the same time, men have an increase in estrogen (the female hormone that’s also found in men), which Vitti said makes them “more emotionally present” during sex. In other words: Men are more likely to actually focus on what you want, instead of jumping straight into the action.

We already know that only about half of women are able to orgasm from penetration alone, so the early morning quickie isn’t exactly ideal. Most women need a bit more than that to orgasm. And, according to Vitti’s hormone theory, you’re more likely to get a guy to go do a bit more later in the day.

The 3 p.m. sex time slot is a bit of a compromise, though. Since testosterone builds over night, men are particularly raring to go in the morning, when testosterone is basically stockpiled in their bodies. But with all those sex hormones surging, the likelihood that a guy’s going to slow things down enough at 7 a.m. (before you’ve have even had coffee) to suit your sexual needs is, um, not great. Testosterone levels lower in men by 3 p.m., meaning they might be in less of a rush. (Plus, no morning breath.)

Sadly, 3 p.m. is a super inconvenient time for most people to have sex, unless your boss is incredibly cool.
