Responsible parenting is telling your children the TRUTH.
Truth is, if you a guy or gal is willing to have sex with you outside of marriage, who else have they been willing to have sex...ie, you don't know where it has been before or what disease it has been exposed to?
Truth is, if you have sex without the benefit of birth control, you are running the risk of procreation...ie, are you ready to be a parent?
Truth is, aim for the best and deal responsibly with the rest...ie, we all make mistakes, but how you deal with the mistakes is a test of your true charactor.
Truth is, no one is perfect...ie, there is forgiveness to be found from those who truly love you.
Truth is, as a loving responsible parent, I OWE THEM THE TRUTH!
