About This Quiz

Sometime between the beginning of time and now, sex became one of the world's most taboo topics. It's not to be discussed in public and is reserved for the most intimate conversations. Talking sex with a stranger is borderline illegal. Having this screen open in public can be nerve-wracking. As far as the media is concerned, depicting sex on TV is blasphemy. Deadly violence is more acceptable.

But as taboo as it has become, it has remained one of Earth's single most important activities. Without it, life as we know it wouldn't exist, so we have to study it. The main issue with a study about sex is that it's a study about sex, and people lie about sex. A lot. The number of people who admit to watching porn has never added up to the amount of money the porn industry makes, but we still have to study it, and we've studied it extensively.

We have stats on everything about sex. We know who's having sex and how long it lasts and where it's going down and how often it's being had. We even have stats telling us who's lying about their sex. Put your sex wits to the test and see what you know about sex.
