Glass is truly one of the most beautiful materials on Earth - and I've been a connoisseur of it for two decades now. I appreciate the smooth, satiny texture, the comforting weight and the elegant of brilliant, radiant crystal. Yep, I'm the kind of guy who gets a hard on from lead crystal stemware! (Don't judge me)

That's why I loved the Moon shine plug - a beautiful, heavy butt-plug made from beautiful glass decorated with a swirl of amber accent. It's truly a thing of beauty - and the reason I nick-named it 'the prettiest paperweight' is because it's such a lovely object it feels almost like a crime to keep it hidden away. I wanted to keep it on the coffee table, proudly on display, but my wife nixed that idea.

So when it comes to the world of sex, it's no surprise that glass toys are amongst my favorite. The smooth texture makes them easy for inserting in any available orifice, while non-porous glass is ideal for sex play as it's totally sterilizable and can be used with different partners - and different holes - between washings.

Glass is exceptionally rigid, so sometimes insertable toys can feel a little uncomfortable to use. This is why small glass toys are generally a smarter bet than larger ones. The Moon shine is sized pretty perfectly.

And glass has the advantage of holding temperature, so what the Moon shine lacks in flexibility, it makes up for by being able to live in the deep freeze or sauce pan - perfect for a little temperature play (there's nothing so intense as an icy plug up the backside.)

The Moon shine has a bulbous head, narrow stem and wide, flared base. Short and reasonably narrow, it's perfect for intermediate anal aficionados and the flange is a good width for making sure it stays safe and secure.

The only possible drawback is that it's unyieldingly rigid, which might make it uncomfortable for some people to use. However the relatively short length and size means most people will be able to enjoy the plug in relative comfort.

The beauty of the design and the accented color swirl make it a true thing of beauty, which definitely adds to the erotic appeal.

One of the best games to play with butt plugs is to leave one in and go about your daily business while 'stuffed.' This is something you might not want to try because of the rigidity of the plug.

However, in the bedroom it's a lovely toy. The smooth texture and modest size make it ideal for anal play - just a little dab of lube - any variety you want, since it's glass - goes a long way to helping 'pop' the little plug into even the tightest of tushes, and in addition to giving a delicious sensation of 'fullness,' the plug also looks pretty buried to the base in a firm, ripe rump.

Glass is the ideal toy material in some ways - you can rinse it with soap, Clorox and boiling water to totally sterilize it, and use any kind of lube you want. If you're happy with the rigidity, glass sex toys make the ideal addition to your collection because you can use them with as many partners as you want (as long as you wash them between uses.)

The Moon shine comes in a lovely velvet bag - a discreet and stylish place to store it. Just like the plug itself, the bag is so nice it's almost a shame to hide it under the bed with all the other sex toys.
