I think that "sex-ed" comes in stages with our kids....Does he know that it takes a mommy and a daddy to have a baby? Does he know that boys and girls have different parts? Introduce him to the ideas slowly.
I have 3 boys and I dont think they ever asked me what the testicles were for, but maybe I just don't remember. I was always pretty open when my kids asked me questions without giving out too much information. They will only ask you what they want to know and really won't push for more information. I would just tell him that the testicles are where his boy parts are kept that makes his penis work, and leave it at that. He doesn't really care yet :)
