What safe things can you put in a vagina?

There are a large variety of items that can be used by women. Clean fingers and hands, penises, and dildos/vibrators from an adult store. If looking for household objects one can use a variety of fruits/vegetables( make sure they are clean and using a condom on them makes it easier), clean closed bottles, ice, and pretty much any hard cylinder provided that it is clean or you put a condom on it.
