Its title may be tired, but the documentary LET‚ÄôS TALK ABOUT SEX is as relevant and necessary as ever in a country that’s schizo about sex, with teens paying the price in crazy rates of pregnancy and STDs. A winner of the Youth Award at the Mostra de Ciencia e Cinema Festival and an official selection of the Provincetown International Film Festival, the documentary (watch the trailer) airs tomorrow night (Sat, April 9) at 10pm on The Learning Channel (TLC). It may be the first show on that channel that’s actually educational and enlightening (hello? Cake Boss? Say Yes to the Dress? I Didn’t Know I Was Pregnant?!?).
