text: i need to find a good book that my 14 yr. old can read about  his body changing.? his been going through puberty for the last year and i dont know how to answer all his questions. i am a single mother of two boys and i need all the answers i can get so when my other son goes through it. thanks honestly i hate tot admitt it but if your son is 14 and doesnt know about him self then u must have kept him in a cave his whole life ...or he doesnt go to public school....but go to your local library they should have plenty of books on puberty
