 Loading... We don't have data for people under the age of 18. Okay What’s your number? What's your gender? Male Female How old are you? How many sex partners have you had since age 18? How do I stack up? 
 
 Don't worry, we're not collecting your data. Data based on answers from more than 13,000 Americans in the General Social Survey, 2006 - 2014. I lied. Let me do it again. 
 
 You, dear reader, are a human being. And as a human being, you are naturally curious, a little bit self-conscious, and maybe even competitive about sex. At some point you’ve almost certainly thought about the number of people you’ve slept with and wondered: Is that normal? 
 
 Wonder no more. Enter your stats into our new calculator, and, based on your age and gender, it will tell you exactly which percentile you fall into when it comes to how many partners you’ve hopped in the sack with. 
 
 Why make a sex calculator? We were inspired by a study published this month in the Archives of Sexual Behavior, which found that millennials (or snake people, if you prefer) are on pace to sleep with an average of eight partners during their lifetimes, fewer than Generation X (10 partners) and the baby boomers (11 partners). In other words, as a group, today’s young adults are shaping up to be less sexually prolific than their parents. But averages—and medians and modes, for that matter—only tell us so much, and when it comes to sex, they also hide the vast array of individual behavior that makes life so darn exciting. So we dove into the same data set that the paper’s authors used, the General Social Survey, and created this calculator to illustrate the full spectrum of Americans’ sexual histories. We used figures gathered between 2006 and 2014 that included answers from more than 13,000 survey takers.

 We noticed a few patterns. First, men generally report more partners than women. Second, these graphs have long right-hand tails, which means a few people in every age group, both male and female, have sex with lots and lots of people. While glancing at the raw numbers, we noticed one man had purportedly slept with 1,000 people. Whoa there, Wilt Jr. 
 
 That’s 1,000 people, by the way, not men or women. Although the GSS does ask participants to count up their male and female partners separately, we decided to combine the answers. Sadly, that means our calculator won’t provide you any info on how your behavior compares with that of people of your sexual orientation, just your age and gender. 
 
 Which brings us to the final issue: These figures are self-reported. People do, once in a blue moon, lie about sex. Memories get hazy. And there were some obvious signs that at least a few survey takers may have been fudging their answers a bit. For instance, round numbers are suspiciously popular. Not a lot of people report having slept with nine or 19 people. A bunch report sleeping with 10 or 20. Beyond that, while the survey asked participants how many partners they have “had sex with” since their 18th birthday, it does not define the phrase, which means people may have interpreted it differently.
– It's a most personal subject: the number of people you've slept with. Here are five ways to see if your number of partners is "normal." Use Slate's new interactive calculator. It aims to tell you if the number of people you've slept with is "a lot." You plug in your age, gender, and the number of sex partners you've had since the age of 18, and, voila, you'll see where you "stack up" against the rest of the population. The questionnaire is short and sweet, letting people decide on their own what to define as a sexual encounter. Calculate your number here. Compare your college self to a Harvard student: As it does annually, the Harvard Crimson surveyed the school's graduating seniors, and found the following: 58% started their freshman year as a virgin; 21% had sex for the first time as a freshman, and 24% had no sex while at Harvard. As for the number of partners, 19% of men and 7% of women had 10 or more during their college career. Check out your generation's average: A recent study in the Archives of Sexual Behavior crunched 40 years of sexual data from more than 33,000 Americans. It projects that millennials—those born between 1982 and 1999—will have sex with about eight different partners in their lifetime, behind Gen Xers with 10, and baby boomers with 12. Consult the CDC: It's a little outdated, but its website shares data from the National Health Statistics Report published in 2012, including the "number of sexual partners in the past 12 months." The most recent range specified is 2006-2010. Men had an average of 3.9 to women's 1.8; partners with whom the respondent had vaginal, oral, or anal sex were counted. Look at this chart: The 2010 National Survey of Sexual Health and Behavior, which was conducted by Indiana University researchers, was self-described as "one of the most comprehensive" sex studies "in almost two decades." It looked at the sex habits of 5,865 people ages 14 to 94 to come up with this chart. While it doesn't specify the number of sex partners, you'll get another sense of where you rank. It shows the percentage of men and women who reported engaging in one of nine sexual behaviors in the previous year. In other sex news, researchers have determined the most dangerous sex position.
