missy hunny,
butt plugs are not that expensive to buy, i got a set of them for i believe about $25, it came with three sizes, very small, moderate, and bigger.. and also came with a vibrator that was ummm even bigger.

just search online for viberators or butt plugs and i am sure you can find them cheap. it would be better than trying the thing in the piccie.. it looks like that would cause some kind of harm.
