You've probably heard that you're more likely to feel frisky around the middle of your cycle, when you're ovulating and your body is telling you to get into baby-making mode. But researchers who set out to further investigate this link (and whether your relationship status affects it) also made another interesting finding: Women who are single are more likely to have sex on weekdays, while women who are in a relationship are more likely to get busy on the weekend, according to a recent study published in the Journal of Sexual Medicine.
For the study, researchers from the University of Catania in Italy monitored the menstrual cycles and ovulation patterns of 1,180 women, then asked them to keep a diary about their daily sexual activity. As expected, the researchers confirmed that all of the women had more sex around the time they were ovulating (and interestingly, this effect was stronger in single women than in those in a relationship). They also found that coupled-up women reported having more sex as the week went on, with Saturday being their friskiest day of the week. Women without a partner didn't experience the same ebb and flow throughout the week and so were more likely than women in a relationship to have sex on Sunday through Thursday.
