What is a flexible spine in a dildo? It is a bendable support that runs through the middle of the shaft. Without one, a soft dildo either droops or has to be made stiff all the way through. The spine lets the toy stay upright while still curving when your body moves against it. In the Au Naturel Jack this is combined with a two-layer build: a rigid inner core gives the feel of an erection, and a soft outer layer gives the feel of skin.
Au Naturel Jack 7 Inch: firm inside, soft outside
The Au Naturel Jack is a realistic dildo that combines two of the maker's technologies, FlexiShaft and Sensa Feel dual density. It has a soft outer layer over a rigid inner core, with a flexible spine through the center. The shaft always feels erect but bends with the motion of your body. It is made of TPE and is tapered for easy insertion and comfortable stretching.
It is 7.5 inches long with 7 inches insertable and a slim 1.5 inch width. The strong suction cup base sticks to any smooth, flat surface for hands-free use, and the toy is harness compatible. This listing is the vanilla tone.
Best for: For people who want length without much girth, and a surface that feels closer to skin than plain PVC. The tapered tip and slim shaft make it approachable, and it serves equally for solo suction cup use or in a harness.

How to use
Wash the dildo in warm water with mild soap and pat it dry. Because the spine is flexible, you can bend the shaft slightly toward the angle you want before you start. For hands-free play, press the suction cup onto a clean, smooth, flat surface. Apply water-based lubricant to the tapered tip and shaft. Insert gradually and let the taper do the stretching. Nearly the whole length is insertable, so set your own limit. To use it in a harness, push the shaft through the ring and seat the base flat behind it.
Care
- Use water-based lubricant only; silicone and oil-based lubricants can damage TPE.
- Wash with warm water and mild soap before and after each use.
- Pat dry with a soft towel and let it air dry completely.
- Do not boil it or leave it in heat or sunlight.
- Store it on its own; soft TPE can react with other toy materials.

Frequently asked questions
What are the measurements?
The dildo is 7.5 inches long, 7 inches of which is insertable, and it is 1.5 inches wide. It is named a 7 inch model after its insertable length, and the maker also describes it as slim.
How does it differ from a single density dildo?
A single density toy has one firmness throughout. This one has a soft outer layer and a rigid inner core, so it gives a little at the surface while staying firm underneath. A flexible spine adds bend.
Does the suction cup hold well?
The maker describes the suction cup as strong. It grips any smooth, flat surface, such as tile, glass or a bathtub. Clean and lightly wet the surface first, and press the base down firmly.
What lubricant should I use?
Use water-based lubricant. The toy is TPE, and silicone or oil-based lubricants can make the soft outer layer tacky or cause it to break down over time. Water-based formulas rinse off easily.
Is it suitable for beginners?
The slim 1.5 inch width and tapered tip make it easier to start with than thicker models. The insertable length is long at 7 inches, but you decide how much of it to use.
