Just buy one. You can get one online or at an adult store.
Haha vibrating back massager, Love that thing, and rubbing alcohol just don't use it right after you steralize haha
hair brush, the part you hold.
shower head (when it's on, obviously)
^I'd personally recommend shower head.
I'd get creative and think of more but I'm feeling rather lazy at the moment.
A carrot works well. It can be carved to the size and shape you like. It doesn't need to be sterilized, washed and peeled will be fine. I assume you know it is a single use appliance. :)
One of my ex-girlfriends used to use a handle of her spatula. Just wash it wish mild soap and water first, and dry it off. I think she would wrap it in cellophane too.
umm they're not that expensive to buy, and it's much cheaper than going to the doctor because you either:
a) got something stuck up there (not to mention embarrassing).
b) get an infection from sticking contaminated objects in your vag.
candle, my ex told me she used that a lot when she was growing up
