IMHO I think that only the two persons that had sex, are totally responsable for themselfs. If you as a parent, raised your son or daughter to be a good and responsable person, you can't help it if they get in trouble anyway.
If you forbid your teens to have sex at your home, they do it somewhere else anyway, and mostly in a hurry, without taking their precautions.
It's not easy being a parent, they forgot to add a manual when the child was delivered. <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" /> You try to do the best you can, some want to do better then their own parents, others follow their parents examples, but either way, you make mistakes. It's only human to make mistakes. But you can't be responsable for your kids their whole lifes.
That is only IMHO. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
