Am I in the wrong?

I'm asking as a mother whats the right way to say to your child and am I in the wrong as my partners parents said to me and him were in the wrong.

Our son earlier can I say he’s 8 was fiddling with him privates I told him to stop touching and that if he wanted to which boys at that ages and girls are curious about there private areas to go do it out of the way in his bedroom so none can see what he was doing.

My question to your is are we in the wrong in saying that what are other people’s opinions
