Well in your world sexual activity outside of marriage is a sin. I don't believe that. Again, if you have a frank and scientific based conversation with your children about sex you wouldn't have anything to worry about. But because you cloud it with words like promiscuity, sin and evil you set up your children and the children of other families for failure. Yeah, talking about condoms and their use with your daughter can be a bit embarrassing but I bet that when she's in her 20's she'll thank you.
