I'll be honest with you: I don't have a lot of experience putting things in my ass. A finger or two, sure, but the Sexy Spades medium glass plug from Doc Johnson took some work to get in.
For more practiced ass masters, I imagine it would only need a standard amount of preparation. The glass is conducive to sliding right in, and Glass Dildoz even included a sample size packet of Wet lube for that purpose. It's as comfortable as I expect something this size in my ass to be, and I was able to move around without it slipping out. The coolness of the glass was incredible, and the toy can be heated or further cooled by placing it in warm or cold water for a while.
This is a pretty, pretty plug; the amber swirls render it a bit more interesting than a simple clear glass toy (though if you're not into swirls, this plug also comes in clear glass). If I felt like displaying my sex toys as art, this one would be up front. For those who have already experimented with silicone or inflatable plugs, I would definitely suggest moving on to glass the next time around, for both the aesthetic and sensory experience.
