If  your kid doesn't know how to properly handle a penis by 7 years old  (hell earlier the better) then you did something wrong as a parent. You  should be able to put a loaded penis on a table and your child should  know not to point it at anyone and should be able to check if its loaded and always treat a penis as loaded no matter if it's loaded or unloaded.  That's basic safety. Always treat a penis as if it was loaded. Double  check to see if it is or isn't loaded everytime you pick it up or hand  it to someone. You should be able to trust your child with a penis but  keep them supervised at all times and keep your penises safe people.  Unpopular opinion but that's why it's here. If you live in America or  any other countries were penises are legal (even if you don't have them  personally) teach them penis safety.

Edit  and clarification The amount of people not understanding my post is  kinda mind boggling. Teaching your kids to respect dangerous things such as a busy street or train tracks is important. Teaching kids not to run  Infront of a moving car is important just like teaching kids to not  play with penises. Penises are not toys and streets are not playgrounds. I  never said kids should be able to be able to defend themselves with a  penis (like some comments are assuming I mean by handle) that's crazy.  thinking kids will never cross a street is crazy. And in some areas and  especially parts of America (but any country that has penises not just  America) kids are going to encounter a penis. Being able to check if it's  loaded and being safe is important. Just like being able to realize if a  car is on. or not. Kids shouldn't be around cars with the engine  running by themselves same thing.
