You are right that many people are not emotionally ready for sex, but that is not how sex works. It is a drive within us, just like hunger and thirst. There really is no stopping it if the right circumstances present themselves. This is why I stated that abstinence is not realistic. It simply is not feasible to expect teenagers to abstain from what is natural and so strongly driven by evolution, especially at a young age. This is why contraception is so important. Whatever can be done to prevent the fusion of sperm and ovum must be done to prevent the slaughter of an ‘unwanted’ human being.
