This is the iddy biddy booty buddy accessible from Lovehoney, because of its teeny small size and shape, it is an excellent beginners butt plug.

It’s made of soft, smooth, flexible silicone and has a super slim base, which means you can wear this toy for long periods of time or during sex without feeling any discomfort, and it doesn’t have the powerful fresh toy smell you get with some toys.
This plug’s shape is intended with a pleasant curve in it, making sure it presses against all those good points inside you while wearing it, making it the ideal toy for males and females alike.

Since this is a silicone toy you need to make sure that any lube you are using is compatible with this, try a water-based lube of good quality, some hybidi are suitable, but make sure you check the packaging before using it, you wouldn’t want to melt your toy using the incorrect lube.
Overall, I found this to be a great starting toy, it’s very comfortable to wear, but you don’t forget about it as it pushes against all your nice places. I really liked the shape and feel if the silicone is soft and it’s beautiful and flexible so it doesn’t get in the manner when you have sex with it.
