Where and how, if at all, should sex education be conducted?

Sex education, I feel should be taught to students at a early age.  Not only for awareness but to educate them about sex and disease.  I think that the earlier their taught  the more understanding they will have.  Sex education in the classroom my help prevent teen pregnancy, sexual transmitted disease's and could very well shape their values and morals relating to sex. it could also teach children that shame doesn't have to be part of sex. it could as well possibly prevent future sex offenders from committing such heinous acts. Awareness is huge for our children. Kids are not dumb. if we don't teach them they will learn or get mislead by other sources.  Sex is everywhere in our society today. On billboard advertising, in TV, our music theres no way around it sex sells. Lets teach our kids. give them the facts.
