The OXBALLS Jerk is a soft, squishy male masturbator with a deeply ribbed inside and a closed end that builds suction with every stroke. Its dumbbell shape stays put in a lubed-up hand, and the brand's stretchy FLEXtpr gives a thick, cushioned feel. This clear version suits anyone who wants a no-fuss manual stroker with real suction and a firm grip.

Suction where you want it

The Jerk is closed at the far end, and that's the key to how it feels. As you push in, air is pushed out; as you pull back, the closed tip pulls against you, so suction builds at the head with every stroke. OXBALLS suggests a simple trick to get more of it: once you're inside, squeeze the sleeve firmly to burp out any extra air around you. The tighter the seal, the stronger the pull on each outstroke. For a gentler session, leave a little air in and keep your grip relaxed.

Ribbed inside, easy to hold outside

The canal is deeply ribbed along its length, which gives a strong, rippling feel as you move. On the outside, the shape is pinched in the middle like a dumbbell, so it stays put in a slippery hand. That matters more than it sounds: most stroker frustration comes from a sleeve sliding out of a lube-covered grip. Squeeze the middle for maximum pressure on the ribs, or hold the ends loosely for longer, smoother strokes.

Soft, stretchy FLEXtpr

Like most OXBALLS toys, the Jerk is made from FLEXtpr, which the brand describes as softer than skin and very strong. It's thick and squishy, at 8 oz in weight, so it has some heft and absorbs your movement rather than feeling hollow. The material is phthalate-free, and in this version it's clear, so you can see what's happening inside.

Size and stretch

At rest it's 6.5 inches long, 3.5 inches wide and 5 inches deep, and it stretches to 9 inches. The stretchy canal accommodates a range of girths. Because it's closed, longer users will reach the end, which adds to the suction but can feel limiting for some. The packaging includes an OXMAN illustration showing how to use it.

Getting started with a suction male masturbator

Fill the canal generously with lube and add some to yourself. Water-based or silicone lube both work with FLEXtpr, so pick whichever you prefer; silicone lasts longer in a sleeve, while water-based rinses out more easily. Enter slowly to let the ribs open up, then burp out the air and start stroking. If it starts to drag, add more lube rather than gripping harder. Warming the sleeve under the tap for a minute beforehand makes the first stroke feel far less of a shock.

Cleaning and storage

Wash it after each use in warm, soapy water, flushing the closed tip well, since that's where lube collects. Turn it upside down to drain and let it air-dry completely. Store it on its own in a breathable cloth pouch or cotton sock, away from other toys.

Helpful Information

Frequently Asked Questions

Helpful answers about OxBalls Jerk Masturbator - Clear.

How do I get more suction from the OXBALLS Jerk?

Once you're inside the Jerk, squeeze the sleeve firmly to push out the extra air around you, then start stroking. The closed tip pulls harder with less air inside. Too much lube can weaken the seal, so add it in small amounts.

What size is the OXBALLS Jerk?

The Jerk is 6.5 inches long, 3.5 inches wide and 5 inches deep at rest, stretching to 9 inches, and weighs 8 oz. It's closed at the end, so if you're longer than the canal you'll reach the tip, which also strengthens the suction.

Can I use silicone lube with the OXBALLS Jerk?

Yes. OXBALLS says FLEXtpr is safe with both water-based and silicone lube. Silicone lasts longer inside a sleeve; water-based is easier to rinse out of the closed tip. Avoid oil-based products, which aren't listed as compatible.

How do you use a male stroker like the Jerk?

Warm the Jerk under warm water, dry the outside, then fill the canal with lube and add some to yourself. Enter slowly, burp out the air for suction, and stroke at whatever pace feels good. Grip the narrow middle for more pressure.

How do I clean a closed-end masturbator like the Jerk?

Rinse warm, soapy water into the Jerk and squeeze it through the ribs, then flush with clean water until no lube remains. Turn it upside down to drain and dry fully before storing; trapped water is what makes closed sleeves smell.

Is the OXBALLS Jerk loud or messy?

The Jerk is manual, so there's no motor noise, though suction strokes can make a slurping sound. Because the end is closed, lube stays inside rather than dripping through, which keeps mess down. Keep a towel nearby for clean-up.
