 While sex education has been linked to a delay in the first time having sex, abstinence-only programs specifically haven't shown this link, and do not seem to influence if or when young people begin having sex.Proponents of abstinence-only sex education argue that this approach is superior to comprehensive sex education because it emphasizes the teaching of morality that limits sex to that within the bounds of marriage, and that sex before marriage and at a young age has heavy physical and emotional costs.In addition, abstinence programs often teach young people that pleasure in sex is most likely to be found within marriage, and therefore, that they should wait to engage in sexual activity until they are married.
