He is growing up- HELP!

Today, my son brought home the dreaded permission slip for the sex education class provided by the counselor at his school.  OMG!- freaking out just a little.  His school counselor is a really wonderful lady and I do not envy her job.  I've hinted (strongly) around to hubby all school year this was going to come up at some point.  What I don't understand is why they waited to do it during the month leading up to the annual testing for his grade.  Once you start talking about this subject no kid will be able to concentrate on school.

I know most parents sign this form and send it back thinking "thank goodness the school is taking care of this topic".   There are a lot of things we leave up to the school, but this AIN'T one of them.  Schools are under so much pressure to keep everyone happy (politically correct).  This means they might not talk about how God created us as man and woman (sorry if you disagree, but this is my house and my blog).  They might hit on abstinence being the only way to prevent STDs or pregnancy, but they don't teach the subject from the stand point of remembering you are a gift and have a gift to give with the person God has chosen for you. 

Several months ago we were presented with a similar situation when our little girl brought home a permission form for the "Good Touch, Bad Touch" program.  Again, many parents don't mind the school teaching this subject, but not us.  Tonight, hubby and I need to have a conversation with our son about what he has already heard/knows (this should be interesting) and why we aren't signing the permission form.   During the last year we have had several conversation about how his body is changing-pimples, body odor, etc.  We have talked about daydreaming and not being able to concentrate-this is very normal at his age.  Please suggest good books on the subject if you have any experience with this topic.  There are several books dealing with the subject and we considering several right now.  I will post a review once we have put one to good use.

Please pray for us as we tackle this topic in our household.  It is really hitting home that our son is growing up.  Pray God will give us the answers he wants our son to hear.
