The Avalon is a double-sided glass dildo. It is designed to be used on either end. Due to its two sides, I would recommend this for just about anyone. One end is great for beginners as it is smooth and relatively thin, and the other side has bubbles or bulges that make it more fun for those that like texture or G-spot stimulation. This would feel great if use anally, but the dildo does not have flared ends. The ends have small bubbles on them about 3.5" in circumference. This dildo is made of glass, which makes it great for temperature play. You can cool it off in cold water or warm it up in a warm water bath. Don't use hot water! It is not huge so storing it wouldn't be a problem, and it would be great for roommate living situations as it is silent!
