I've been looking at the plethora of books about puberty & sex on Amazon ... especially those for boys ... but they're all coming up short. I don't want something that spends half the book talking about masturbation, HIV, sexual abuse, or alternative lifestyles. I want something that mostly just gives the "how will I change" and "how does it work" information in a matter of fact way (preferably illustrations), with either implied or stated abstinence. Perhaps something from a Christian publisher? We use Abeka for health, but I haven't seen anything like what I'm looking for yet (I have or had grades 1 thru 7). It would also be nice to find a book for boys that also discusses the basics of changes in girls. Suggestions?
