The newest study to surface in what we like to call, "No Way!" science is the age you lost your virginity might be genetic. Researchers at California State University think "sexual precociousness" is an innate personality trait, and that you may come from a long line of lost-it-at-18ers. Or 19. Or 14. Or 25. This is presumably to secure sure there's always The Slutty Girl and The Class Virgin, we guess.

Nancy Segal, the lead researcher in the study, admits that science will never be able to predict when one will lose their virginity by staring at cells on a microscope. Of course, it's much more complicated than guessing height or weight. Promiscuity and early sex, they note, can be pinned on a variety of environmental issues.

After studying 48 pairs of twins separated at birth and 23 individual twins, researchers theorize genes explain a third of the reason why people lose their virginity at a certain age.

Societal norms and how culture views pre-martial sex also highly skews the results. The scientists noted that girls in particular use sex as a form of rebellion, having more of it an earlier when they feel "unhappy and unfulfilled" at home.

Regardless, while first sexual experiences may be too incalculable to draw stop the presses results, they all agree a strong presence of the impulsive, risk-taking DRD4 gene promotes earlier bed-hopping.
