I work in the Chicago Public School system, where the "they're going to do it anyway" is rampant, and suggesting otherwise seen as "creepy." At the school of a colleague (at a different school) and fellow parishoner, Planned Parenthood and some other ilk passed out sex brochures to the kids as they left school. My friend was just going to be married, he told his class how he didn't agree with the brochures on "just do it," and that when he got married the next month it would be his first sexual experience (he since has 4 children, and his wife one time was talking about how she enjoys sex (in the context of the discussion, it was appropriate), so it wasn't his last). He figured he would get a response, and he did, just not the one he expected: a great number of the parents contacted him and told him the impression that he had made, and the parents approval and gratitude for him speaking up.
