I have a glass butt plug about the same girth, but it's much shorter, and while it's great for wearing long periods of time, I decided I needed something that felt more violating. The big end was it, and it's a great butt plug. It's just the right length and girth (that is, for individuals who are a bit experienced, it's surely too big for beginners, so don't even bother). It's actually just long enough that I just barely run out of room for it. But this is exactly what I wanted.

This is silicone, and it's very flexible. The base is huge so you'll never lose the plug, but it's still soft enough that it's not uncomfortable. The neck is lengthy too so you have space and your butt's not being squeezed between the base and the plug. The silicone is very pretty, not just a solid charcoal color, but it swirls a bit and glistens. The base is particularly beautiful, giving a lovely view to anyone who might find themselves behind you. This plug holds on to smells a bit, but this is fixed with a good wash. As with any silicone, easy to wash and disinfect, easy to warm up. Use with water based lube only, and you're not going to need a lot either because this butt plug is very smooth and goes in easy.

I'm used to my glass plug, despite it's thickness, I sometimes wear it for a while and forget it's even there. With the big end, I wore it for three hours and was always aware of it. This is not a negative for it, but something to be aware of it. It's a comfortable butt plug despite this. this butt plug makes for great warm-up for large toys, and great for sub-dom play.
