I love my inflatable butt plug, and I am liking these beads also. Got them yesterday and tried them. Now this morning I have them in again, as I type. They are longer than the plug, so more penatration. I can get the whole "string" in, so just the wire and the hose are left going out my hole. Then when I pump it, it is all expanding up inside. If you don't have all of it in you, a bubble will start on the outside too. Sometimes it is slow to release, that is exciting! I just pull on it a little and it releases. About 8-9 pumps is all I can take right now. If you like expanding plugs, I think this will please you also.
