Yes. That time in a child's life is very important! It develops their mindset of what is right and what is wrong. These kids are very egotistical and by introducing this topic early on and making it become less of a taboo for those who have been in unhealthy relationships or who have had sex will allow them to be more understanding of others and reduce the possibility of pregnancy. All they know is that sex feels good and teaching them abstinence only is not a good way to go about that. Leave a 5 year old in a room with a cookie jar alone and tell them not to touch it. What is going to happen. Teenagers are capable of understanding this, don't teach one perspective.
