OxBalls Ergo Butt Plug - Smoke Medium

The OxBalls Ergo Medium is a smooth silicone butt plug with a kidney-bean shape that's made to stay in comfortably for longer sessions. In translucent Smoke, it's the middle of the five Ergo sizes, a good fit if you already enjoy average-sized toys and want a plug that fills you up without being a big stretch.

A kidney-bean shape that settles in

Ergo's profile is rounded and slightly curved, like a kidney bean, rather than a straight cone. The body tapers down to a neck that's much narrower than the bulb, so once the widest part passes, your muscles close around the neck and the plug sits there without pushing back out. Below the neck, a flared base with soft silicone flanges rests between the cheeks. That base stops it travelling further in and is comfortable enough to sit on, which is why OxBalls pitches Ergo for long wear rather than a quick in-and-out.

What the platinum silicone feels like

OxBalls pours Ergo from its Pure Platinum Silicone, which is 100% silicone and phthalate-free. It's dense but has a fleshy, slightly "blubbery" give, so the surface softens a touch under pressure instead of feeling like hard plastic. The finish is very smooth, with no seams or texture, so it slides in evenly with lube. Each plug is hand-poured at the OxBalls factory in Los Angeles, which means the smoky translucent colour varies a little from one piece to the next.

Choosing between Ergo butt plug sizes

Ergo comes in five sizes, from X-Small to X-Large; we carry the Medium and Large in Smoke. The useful number is the largest usable circumference, because that's the stretch you feel as the bulb goes in. Wrap a soft tape measure around the widest point of a toy you already enjoy, then compare: Medium tops out at 6.5 inches around, Large at 7.5 inches. Both are bigger than a starter plug. Medium suits people who are comfortable with average-sized toys and want a satisfying stretch; Large is for experienced users who enjoy a heavy, full feeling. The weight jump is noticeable too, from 8.3 oz to 12.1 oz, and heavier plugs press more on the walls when you stand or walk.

Lube and getting it in

OxBalls lists water-based, hybrid and oil-based lube as safe and advises against silicone lube on its silicone. A thick water-based or hybrid formula works well for a large plug, since it stays put while you go slowly. Warm up with fingers or a smaller toy, coat the plug generously, and press in with steady pressure while you breathe out. Pause at the widest point if you need to; once it passes, the neck pulls it home.

Cleaning and storage

Wash it in warm soapy water after each use. OxBalls says Ergo is dishwasher safe, handy for a thorough clean, though a top-rack run with no harsh additives is the gentle option. Store it on its own in a cloth pouch or a clean cotton sock so it doesn't touch other toys.
