Is a thick dildo more comfortable when it is soft? Often, yes. Girth is the measurement people feel most, and a thick toy made from one hard material can be unforgiving. The Fat Boy uses a dual density build: a soft outer layer that compresses a little as it goes in, wrapped around a rigid core that keeps the shape. The cushioning makes the extra width easier to take, while the core and spine stop the dildo from bending away. Generous lubricant and a slow start still matter with any thick toy.
Au Naturel Sensa Feel Fat Boy: girth with give
The Sensa Feel Fat Boy is the wide-bodied dildo in the Au Naturel line. It is a 7 inch dildo with 5.5 inches of insertable length and more than 5 inches of circumference. The Dual Density Sensa Feel build places a soft outer layer over a rigid core, a structure meant to mimic how the body feels.
A flexible spine inside keeps it erect and makes it posable, so you can curve it to suit your shape and it will follow the body as you move. The material is body-safe, phthalate-free TPE, and the dildo is harness compatible.
Best for: Meant for people who know they like girth and want a filling dildo that is still soft to the touch. It suits experienced users more than first-timers, and couples can use it in a harness that takes a wide shaft.

How to use
Wash the dildo with warm water and mild soap and pat it dry. If you want a curve, shape the shaft gently and it will hold. Warm up first with fingers or a slimmer toy, because the width is the demanding part. Use a generous amount of water-based lubricant on the dildo and on yourself. Ease the head in slowly, pause, and let your body adjust before taking more. Add lubricant whenever it starts to drag. In a harness, choose an O-ring sized for a thick shaft and check that the base sits securely before you begin.
Care
- Use water-based lubricant only; other types can damage TPE.
- Wash with warm soapy water or a toy cleaner before and after every use.
- Pat dry with a soft towel before storing, and never boil it.
- Avoid sharp, repeated bends that could strain the spine.
- Keep it apart from other toys, away from heat.

Frequently asked questions
How thick is the Fat Boy?
The maker gives it more than 5 inches of circumference. The width is stated as 2 inches in the description and 2.2 inches in the feature list, so expect a diameter of roughly 2 inches or slightly more.
How does it differ from the standard 7 inch Sensa Feel Dildo?
The length and the 5.5 inch insertable length are the same, and both use the soft outer layer, rigid core and posable spine. The Fat Boy is the girthier of the two, built for people who want more width.
Is it suitable for beginners?
It is better as a second or third dildo. The soft outer layer makes the girth more forgiving, but over 5 inches around is still a lot. If you are new, start with a slimmer toy and work up.
Will it fit my harness?
It is harness compatible, but the shaft is thick. Check that your harness takes interchangeable O-rings and fit one of about 2 inches or larger so the dildo passes through without being squeezed.
How do I clean it?
Wash it with warm water and soap, or a toy cleaner, before and after every use, then pat it dry with a soft towel before storing. Stick to water-based lubricant, which will not harm the TPE.
