Ok, so I'm a size queen. I got this mainly cuz it was cute and on sale, but wasn't expecting much from this since it's under 5 inches. Boy was I wrong! The girth and shape is such a different and unique sensation from what I'm used to but it's very FILLING! Not for the faint hearted, lol. The base "locks" in like a plug so it stays inside you. I used it with a clit vibrator and climaxed almost immediately.
