The Centers for Disease Control and Prevention has done some "high-tech research" (makes you wonder, huh?) and concludes the following….

  • Sixteen percent of adults first had sex before age 15, while 15 percent abstained from sex until at least age 21.
  • The
    proportion of adults who first had sex before age 15 was highest for
    non-Hispanic blacks (28 percent) compared to 14 percent for both
    Mexican-Americans and non-Hispanic whites.
  • Six
    percent of blacks abstained from sex until age 21 or older, fewer than
    Mexican-Americans (17 percent) or non-Hispanic whites (15 percent).
  • Black
    men and women were more likely to report having 15 or more partners in
    a lifetime (46 percent and 13 percent, respectively) than other racial
    or ethnic groups.
  • 29 percent of American men report having 15 or more female sexual
    partners in a lifetime, while only 9 percent of women report having sex
    with 15 or more men.
  • Seventeen percent of men and 10 percent of women reported having two or more sexual partners in the past year.
  • The survey found only about 11 percent of never-married adults had remained chaste.

And the number I found most encouraging…

  • Twenty-five percent of women and 17 percent of men reporting having no more than one partner of the other sex in their lifetime.
