I must admit the first thing that went through my head was a question about whether he was physically up to the deed or not. I have raised two sons and don't think either of those would've been at 12, both of them having still been very small in height and with unbroken voices so clearly not having started puberty. While I didn't ever see private areas of them much past them being 5 or 6 (and even then it only being by accident) I still don't think a 12 year old, unless physically very mature like one of one of my son's friends could've been as he was 6ft tall at 12, would've been up to it. I think there's a good bit more to this than meets the eye. DNA test time I think.
