Sex ed should be taught in schools because it teaches students to make responsible choices. Abstinence is heavily pushed in sex ed classes so it's not encouraging sex and the teaching of birth control is just to prepare students for when sex does happen. Teenagers are hormonal and if not taught properly like by parents they are likely to have sex and not be safe. Likely to catch STDs or get pregnant. Sexual education is important for teenagers because they need to know the facts not just something they found on the internet that is likely to be wrong.
The affirmative has raised several points regarding the benefits of sexual education within schools. They said that sexual education encourages abstinence and teaches hormonal students about STD's. They also stated that parents are not able to teach kids properly. As the negative, I fail to see how parents (who have raised the child from birth) are less equip to educate a child about sex than a teacher who knows virtually nothing about the child's physical, emotional and social state.
Sexual education teachers teach hundreds of students daily and find it impossible to meet the needs of every student. For example, teaching methods applied on a virgin should be different to a person who has had sex before. In sexual education this is not the case.
It is important for teenagers to know the facts. I believe that sexual education can provide these. However, the correct relaying of these facts to each student is also essential and sexual education cannot possibly provide this.
