I absolutely love the idea of a strap-on dong having a bullet that you slide in the bottom for added stimulation for the other partner. If using this anally or with multiple partners a condom is a must. Not only protecting the toy against germs but also each of the participants from who knows what (using a different condom for each player). This has a 4 inch girth with a flared base for a strap-on use and can be used solo as a dildo type toy. It's not a butt plug, but it is tapered at the head making it for easy and comfortable anal insertion.
