Now that is a major assumption, innit .. that also to support the argument that its ok for kids to learn the name of sexual organs at the age of 6
The point was that the kids know what its called in English; why does he want to know what the translation is in different languages ?
A 6 yr old will not know that those are sexual organs. All he/she will know is that he uses those organs for peeing. However, if thats not the case there is a problem far bigger than just knowing the name.
