I have two boys 7 and 9. The younger one talks about penises all the time in a joking way (like he'll sing "Penis, penis, take out your penis!) and he has done this for years. The older one, the more shy reserved one, will laugh at his younger brother's penis jokes but on his own, he seems very ashamed of his body, and at this age will not let me see him in his underwear (I know this is normal for his age). Both of them say they are disgusted by girls and girls things (again a fairly normal reaction although it doesn't help that the school they go to is all boys until 8th grade...I would transfer them, but there isn't a really good alternative right now). Both of them have already talked to me about having an erection. A very progressive parent told me about a book called "The Guide to Getting It On" which she got her 8 yr old. Seems a tad too much too soon for us. When I looked on Amazon, I don't see a whole lot for tweens other than some moralistic books that include the staple "peer pressure" and "stay away from drugs" conversations about body consciousness. Is there some fun way of opening the gates for my kids to explore their sexual truths that is not too much all at once?
