You couldn't be father from the truth and/or reality. Fourteen year olds, even when phyically well developed, have no , NO " right " to engage in sexual intercourse. They can't drive, they can't vote, they can't go into the military, can't get a job ( except for baby sitting or snow shoveling or some such ) without their parents' permission, they can't legally wed, they can't buy alcohol nor tobacco legally, can't sign a contract of any sort and yet YOU think it's pkay for them to engage in sexual activities ?
And, " knowing the consequences of a teen pregnancy " is one of the least prerequisits of the matter. These children are belligerent, have lawyers who blame it all on ADD, parental abandonment ( my guess iis children of divorce ), and a passel of other garbage. They are incorageables. And yet, YOU want to " let them just do it " ? Are they base animals, or human beings ? You act as though they are wild beasts.
