...where abstinence-only education reigns supreme, some high school girls are taking sex-ed matters into their own hands.

Case in point: Two new films, "Toothpaste" and "The Education of Shelby Knox."

"Toothpaste" (a reference to teen slang for condoms) is a 16-minute educational film promoting condom use, produced by four teenage girls from south Texas in response to high teen pregnancy rates at their school. It features two teen girls' decisions on whether to have sex with their boyfriends. One decides to wait. The other has unprotected sex. The film is available to Texas public schools, and has been ordered by schools around the country.

"The Education of Shelby Knox" is a documentary that follows a Texas teenager's transformation from vowing "sexual purity" to realizing that many of her classmates are sexually active. Knox finds her calling: promoting comprehensive sex education in the “abstinence-only” Lubbock public schools. The filmmakers follow Knox as she takes on the town’s officials and religious leaders, challenging them from the bedrock of her own Christian beliefs.

Planned Parenthood of New York is screening "The Education of Shelby Knox" in NYC tonight. It's also airing on PBS on June 21.

"Toothpaste" will be shown at various film festivals and on Showtime.
