It's good for your daughter to choose abstinence but not all young people will do so. Adolescents should learn about the risks of various kinds of sexual activity and safe-sex alternatives before they become sexually active. Sexual ignorance can result in unwanted pregnancy and sexually-transmitted disease.
There are no safe-sex alternatives. Condoms fail some 10% to 15% of the time, and provide no barrier to many viral sexual diseases. Kids have been taught lies about safe-sex for many a year. The explosion of VD (things like drug-resistant, untreatable gonorrhea, herpes, papillomavirus (which causes cancer)) is an indication of that. And then, or course, there's the abortion thing. Kids and adults who think one can simply get an abortion (murder) when safe-sex doesn't work, and that there will be no psychological and long lasting consequences are horribly fooling themselves.
