Except now with protection kids will be less worried of the consequences and will have even more love.
You can argue chicken or egg all day, but it's a good thing.
I would not want my 12 year old child to be having love.
But, I couldn't keep watch of them every minute of every day until they're of legal age.
So, I would trust my child to not go and have underage love, but if they are going to, for whatever reason, I would rather have them be safe and do it than not be.
The lesser of two-evils is a safe loveually active child, rather than a loveually active child with diseases and causing pregnancies.
