What happens inside your brain and body during an orgasm? A whole lot. Orgasm in both men and women is a heck of a lot more than just a few genital contractions. The video below, entitled The Science of Orgasms, will walk you through just a few of the many changes that happen. The most fascinating part is where they explore the vast number of cognitive (e.g., loss of reasoning and control) and emotional changes (e.g., reduced anxiety and aggression) that occur upon reaching climax and how they differ across the sexes.

This video also highlights a couple of important and well-known sex differences in the nature of “the big O,” including the fact that female orgasms tend to last longer than male orgasms (20 seconds vs. less than 10 seconds), and that women have the ability to reach multiple orgasms. Isn't science fun?
