Soooo butt plugs..

My bf randomly brought up the idea of me getting a butt “thing”. But he wants it to have a tail... do butt plugs actualy do something for the female or is it weird feeling?? Should I be worried he wants it to have a tail?? Lol.

Also I don’t know where to get those types of things. Nor do I know what to look for. So any sites you maaay know of. Please suggest.
