I've had a few butt plugs but never anything that vibrated, so I thought I'd give this a go because it isn't much bigger than any of the other butt plugs I have. I loved the double bulb design cause I could really feel it pop as I inserted it, and the silicone is so smooth, so inserting it was easy with a little lube. I could really feel it, but in the best way! Definitely the best introduction to vibrating butt plugs. Bonus was that the bullet is removable, so it was really easy to clean afterwards, and I can use it for other things.
