The Teen Sexual Revolution by Kerby Anderson:
"A 1992 study by the Centers for Disease Control found that 43 percent of teenagers (age 14 to 17) had engaged in sexual intercourse at least once."
"The study was presented at the Ninth International Conference on AIDS held in Berlin on June 9, 1993. The study involved 304 couples with one partner who was HIV positive. Of the 123 couples who used condoms with each act of sexual intercourse, not a single negative HIV partner became positive. "
"A New York Times article reported: "Some studies indicate three-fourths of all girls have had sex during their teenage years and 15 percent have had four or more partners." A Lou Harris poll commissioned by Planned Parenthood discovered that 46 percent of 16-year-olds and 57 percent of 17-year-olds have had sexual intercourse. "
"One New York polling firm posed questions to 1300 students in 16 high schools in suburban areas in order to get a reading of "mainstream" adolescent attitudes. They discovered:
57% lost virginity in high school
79% lost virginity by the end of college
16.9 average age for sex
33% of high school students had sex once a month to once a week
52% of college students had sex once a month to once a week. "
