The Atlas is completely smooth with no curve. It is slightly wider at the tip than at the bottom of the shaft, but this is a gradual enlargement. This toy is amazing! I'm overall an intermediate toy user, but am still rather new to thrusting. Toys with a more "unique" texture can be intimidating, and I'm not a huge fan of curved toys (pressure on the spongy region of the front vaginal wall aka the"G-Spot" usually just makes me have to pee), so of course I had to try this one!

With a little lube and a naturally wet orifice, this bad boy slides in and out with ease. The base seems to fit perfectly in my hand. It offers a fantastic feeling that leads to explosive orgasm.

Since it is made of glass, it doesn't release harsh chemicals and can safely be boiled to sanitize. It can also be used with any type of lube. Also, as with all glass toys,it can be pretty cold and takes a few minutes to warm up.

If you strongly prefer lots of texture and/or more girth, this might not be for you. If you're looking for something simple, ease to use, slender, straight, and smooth -I would HIGHLY recommend The Atlas. Even more experienced toy users may appreciate its simplicity and smooooth texture. Unless you know for sure that you need bumps or ridges or a large size, give this a try!

As far as anal play goes -- I wouldn't risk it. There is a small base, but there isn't an area that's smaller than the base and the shaft between the two. This is usually present in anal toys to help keep them from slipping in or out of place.The base is smaller than the shaft of many toys made just for safe anal insertion. It's a worry that shouldn't have to be present duning playtime.
