Also, ever heard of HIV and AIDS? About how it spreads through free sex? I am not discriminating against kids who have it since they were kids, they are not at fault here, they were born without sin, but it was the sin of their parents. Their parents should be hold responsible for that.
You as parents may not have felt the consequences, but your child is the result. So be responsible. You put him/her into suffering in the future because you want to satisfy your lust now. Why must you be like that? You never think about future, you're trapped in today, and never thought in long-terms. Pathetic.
You can repent, but once you've already done it and the consequence is already there, you have to deal with it, like it or not. You have to learn from it.
