Sex, Hispanic | featured news

More than 20 percent of black and Hispanic teens say they have used their cellphones to send a "sext" message showing a nude or semi-nude photo or video of themselves to another person, and more than 30 percent say they have received such sext messages, according to a new study.

More girls in the U.S. are remaining virgins until their late teens and into their 20s, with the biggest rates of decline in sexual activity seen among African-Americans and Hispanics, the CDC says.
