I was nervous about trying anal play for the first time, but the 3" size was perfect for starting out. The silicone has just enough give to it, and cleanup takes about a minute with warm water and soap.
I was nervous about trying this for the first time, but the soft silicone is so forgiving that I didn't feel any discomfort at all. Even the 3.5 inch middle size slid in with just a little lube, and the base sits flush enough that I forgot it was there after a few minutes.
The tapered tip made insertion so smooth and easy that I hardly had to think about it, and the base sits flush enough that wearing it around for a while felt totally secure. Even though I'm not super experienced, the 3-inch size was gentle but still gave that satisfying "naughty" fullness.
