........so will he really be missing anything if I don't give permission for him to have them? He fully understands the 'science' side of reproduction so that isn't an issue. All he will say is that he really doesnt want to attend and it will be all about penises and stuff!
I've also bought him some books on the subject and about puberty/body changes - he was upset with these too and has hidden them in his room somewhere - I've looked and can't find them!
