So according to the Huffington Post, 485 people surveyed couldn't agree on whether they'd had sex or not. Apparently 89% of people said that penile/vaginal sex is only sex if the guy ejaculates! I used to try that line on my girlfriends in high school (come on honey, just let me stick it in for a few minutes, it doesn't count!). So NR, what's sex to you?

Oral Sex: Yes/No
Anal Sex: Yes/No
Sex with Ejaculation: Yes/No
Sex with Ejaculation but no female orgasm: Yes/No
Mutual masturbation with dual orgasm: Yes/No
Something I'm missing: Yes/No

Let's talk about sex.

But first, it might be useful to define it.

More than a decade after Bill Clinton raised questions over the definition of the word "is," a new study is raising questions over the definition of the term "had sex." If you ask men near the same age bracket as the former president (over 65), 23% wouldn't even count penile-vaginal intercourse.

Research conducted by the Kinsey Institute at Indiana University found "no universal consensus on which behaviors constituted having 'had sex.'" Questions in the telephone survey of 486 random participants asked about different behaviors: manual-genital, oral-genital, penile-vaginal intercourse and penile-anal intercourse. The study also looked at different outcomes and qualifiers, including orgasm in women, ejaculation in men, short duration, or wearing condoms.

For example, 89% of respondents considered penile-vaginal intercourse as having "had sex" only if the male ejaculates. Without any qualifier mentioned, 95% felt that penile-vaginal intercourse counted.

What's the standard for the remaining 5%? Not to mention all those older men?

Perhaps some respondents were in denial, or perhaps researchers were wary of too much information. Either way, the study apparently didn't get that specific. But it did find a need for behavior-specific terminology in certain fields. The institute concluded, "Researchers, educators and medical practitioners should exercise caution and not assume that their own definitions of having 'had sex' are shared by their research participants or patients."
