I caught my 11-year-old son naked in the back pool with a girl!?

maybe its as simple as his pants ripped or he could know far much more than you think he does and they was simply having a bit of ual fun, this could have been by a hand job or a ********. iits up to you what you think about it, but really you should talk to your son about this, as he will be the only one who knows the truth, and he is more likely to tell you the truth if you have punished him.
