One in five US teens has sent nude or partially clothed images of themselves to
someone by email or mobile phone and twice as many have sent sexually suggestive
electronic messages.

More than 30 percent of girls in the United States
become pregnant before they reach age 20, and many become pregnant a second time
before their 20th birthday, according to NCTUP.

According to the
Guttmacher Institute, nearly half of all 15- to 19-year-olds in the United
States have had sex at least once.
