As for 10 year olds having sex, I cannot and do not even want to think about it. I'm sure most people here know/knew where their young children were and who they were with. My major pet peeve with parents now is that I see far too many, far too many who do not understand that parenting is sacrifice. It is rewarding. I think the greatest word I've ever heard or will ever hear is "dad". But, as I am sure you know, parenting is hard work. It is about giving up many of the things you enjoyed prior to having kids. It's about being the example for your children to follow. It is sacrifice, even the little things.
I don't understand how a 10 year old has the freedom to have sex. Sadly, society seems not to want to deal with it if it costs money.
