Zollner's confusion and ignorance about sex is all the more inexplicable considering that, as a U.S. teen, he has enjoyed a substantial amount of exposure to the subject. Among Zollner's many sources for sexual imagery and information are rap videos, the 1999 film American Pie, the St. Louis Rams cheerleaders, the midriff-baring outfits worn by female classmates at school, hundreds of hours of school-hallway and locker-room talk, and the videotape Your Body And You, which was shown to Zollner's health class on the last week of freshman year by physical-education teacher Greg Erstad.
