The best time of the day to have sex is 3pm, according to hormone expert Alisa Vitti.
She was quoted by Daily Mail Online as saying that that is the time "when men and women are most in tune with each other's desires".
Ms Vitti, who's also an integrative nutritionist and author, says that women are most energetic at 3pm due to high levels of costisol, a steroid hormone which helps alertness.
As for men, their elevated oestrogen levels at this time make them "more emotionally present". Despite a dip in their testosterone levels, 3pm still makes for a "perfect compromise" because men are better able to focus on a woman's needs, Ms Vitti said.
She added that the best time of the month to have sex is during the ten days or so after ovulation. According to her, this is the period when a woman's desire skyrockets due to a surge in oestrogen and testosterone. At this point, women "feel way more appreciative of receiving pleasure".
