1. Women are happier with less attractive men. A 2017 study found that if the male was less attractive than his wife, he was much more likely to compensate with gifts, sexual favors and doing chores around the house. Unsurprisingly, that lead to higher marital satisfaction for the wife.
2. Most of us are trying to date out of our league. According to a study published in August 2018, users of online dating sites spend most of their time trying to contact people out of their league. Researchers found most online daters tend to message people exactly 25% more desirable than they are, although women are a bit less aspirational than men.
3. Men having affairs are more likely to break their penis. Men, be wary of those 5 p.m.-to-7 p.m. relationships with someone who’s not your spouse: According to a 2011 study, cheating may make a man more likely to suffer from penile fractures. Researchers looked at men who “broke” their penises and found that half were having extramarital affairs at the time.
4. That sexual afterglow you feel after sex lasts 48 hours. You’re generally in a better mood after sex, thanks to a flood of endorphins and other feel-good hormones released post-climax ― aka, sexual afterglow. In 2017, researchers from Florida State University found that the positive effects of getting laid last up to two days ― and that the feeling can help couples bond over time.
5. Couples who share chores have better sex lives. Pitching housework to your partner seems supremely unsexy, right? Next time you do it, mention this study finding: In 2015, researchers from the University of Alberta found that couples who divvied up chores had higher relationship satisfaction and had more sex than couples who didn’t mutually contribute.
