Hair brush handles, small bottles you will be surprised at what comes to mind if you start looking around your house with some naughty thoughts ! Make sure that you can clean whatever you use thoroughly, you don't want any nasty infections and also use a condom over top of the item. Remember with fruits and vegies that you have to wash them as well for the same reasons you do before you eat them.

As for the toothbrush Tojo, would that be the oral care kind ? :P
