You can tell a lot about a person's sex life…from their hips? Apparently so! A new study published in the Archives of Sexual Behavior claims that a woman's hip width has a significant impact on her sexual behavior. Well, that's one I've never heard before!

Researchers enlisted 148 U.K. women between 18 and 26 years old and measured each participant's hip width. They then compared those numbers with their sexual history, such as the age of their virginity loss, number of sexual partners, etc. And you'll never guess what they discovered!

The study concluded that hip width was directly correlated with how active your sex life is. The strongest association? The greater the hip width, the more frequent the one night stands! Uh, alrighty then.

I'm pretty sure that we, not our bone structures, determines our sex drive. But it is an interesting correlation, nonetheless. And it's hardly the first time that researches have examined the body to get clues about one's sexual past. Below, check out what else various body parts can tell you about your sex life, according to science:

Men who prefer small breasts are reportedly financially secure, aren't interested in fatherhood, and are less sexist than those who prefer large breasted women. Guys who like bigger breasts apparently do so because (whether they realize it or not) it reminds them of motherhood!
