How does a penis extender sheath stay on? A sheath is a hollow sleeve worn over the penis, with a solid tip that adds length and walls that add girth. This one stays put in two ways. The inside is ribbed, and those ribs create suction against the skin once you are fully in. A stretchy strap at the base then loops behind the testicles and anchors the sheath to the body, so it does not slide off during thrusting.
Performance Plus 10 inch sheath: more girth, more length
The Performance Plus 10 Inch Sheath is a wearable penis extender with a smooth, realistic look. It is 10 inches long overall and 2 inches wide, with a 7.25 inch inner channel for the wearer. According to the distributor it adds girth and 1.5 inches of extra length. It is made of platinum-cured silicone that is free of phthalates and latex.
Ribbing inside the sleeve creates suction to keep it in place and adds sensation for the person wearing it. A ball strap at the base gives a second point of hold: the testicles pass through it, and it keeps the sheath from sliding forward.
Best for: For couples who want to try a larger size during penetrative sex, and for wearers who like the snug, ribbed feel of a sleeve. Of the two Performance Plus sizes on this site, this is the shorter one and the easier place to start.

How to use
Wash the sheath inside and out and dry it. Put a small amount of water-based lubricant inside the sleeve and on your penis. Once erect, slide your penis into the sheath until it sits at the base, pressing out any trapped air so the ribs can grip. Stretch the ball strap and bring your testicles through it one at a time. Check that the strap feels snug but not painful. Lubricate the outside generously before penetration, and tell your partner to speak up if the size is too much. Remove it if you feel numbness or discomfort.
Care
- Use water-based lubricant only, inside and outside the sheath.
- Wash with warm water and mild soap after each use, and rinse the ribbed interior well.
- Let it dry completely, inside included, before storing.
- Store it flat and away from other silicone toys.
- As general guidance, do not wear the ball strap for longer than about 20 to 30 minutes at a time.

Frequently asked questions
How much length does it add?
The distributor states 1.5 inches of extra length for this 10 inch model, along with added girth. An older description of the same product gave half an inch, so treat 1.5 inches as the maker's current claim.
Will it fit me?
The inner channel is listed at 7.25 inches and the outside is 2 inches wide. Silicone stretches, and the ribs and ball strap hold it in place on a range of sizes. A full erection gives the most secure fit.
What is the difference between the 10 inch and 11.5 inch versions?
Size only. This one is 10 inches long with a 7.25 inch channel and adds 1.5 inches. The 11.5 inch version has an 8.75 inch channel and adds 2.5 inches. Both are 2 inches wide.
Which lubricant should I use?
Water-based. The sheath is silicone, and silicone-based lubricant can damage it. Use a little inside to help you slide in, and more on the outside for your partner's comfort. Reapply as needed.
How long can I wear it?
The ball strap fits snugly around the testicles, so follow the general guidance for ring-style toys: about 20 to 30 minutes at a time. Take it off sooner if anything feels numb, cold or painful.
