Oxballs 4.75 Inch Tunnel Plug review

Squishy-soft platinum silicone that gives you a real sense of fullness without the pointy tip or skinny stem that makes other plugs uncomfortable after an hour. Reviewers consistently say it takes a bit of effort to get in, but once it's there it stays put and feels exactly like what you wanted.

This is what reviewers call a "chunky" plug — wide enough that you know it's there, soft enough that you forget about it once it settles. The silicone has a slippery quality that sets it apart from firmer plugs; one reviewer who owns several Doc Johnson pieces says the Oxballs material feels noticeably more comfortable and easier to live with.

The shape matters here. No tapered tip means insertion asks more of you than a graduated plug would, and the soft silicone compresses rather than slides — so you push from the neck rather than the base, and you take your time. Reviewers who've worked up to this size say it's worth the effort, because the trade-off is a plug that doesn't dig in anywhere and doesn't remind you it exists every time you shift position.

The fullness is the point. The head sits wide enough that you feel properly filled without needing length, and the hollow centre keeps the weight manageable. One Reddit user put it plainly: "quite big so it gives a sensation of feeling full despite not being a tall plug." That's exactly what it's designed to do.

Long-term wear is where it earns its keep. Reviewers who've tried both say softer plugs are harder to insert but easier to forget about once they're in, and this one delivers on that. The base sits flat, the silicone stays put, and the lack of a thin neck means there's no pressure point that starts to ache after an hour.

If you've worked up to intermediate sizes and want something you can wear comfortably for a few hours, this is exactly that. The fullness and the soft silicone make it ideal for anyone who finds firmer plugs uncomfortable after a while, or who's discovered that a skinny stem just doesn't work for their body.

Beginners should look elsewhere. The wide head and the soft material mean insertion takes patience and a fair bit of lube, and if you're still getting used to plugs generally, a firmer graduated design will be easier to work with. This one rewards experience — you need to know what you're doing to get it in without frustration.

If you're after something for active movement rather than static wear, consider a firmer option. The squish that makes this comfortable also means it can shift more than a rigid plug would, and some reviewers note that softer toys need a bit more attention during insertion. But if your intent is to put it in and forget about it for the afternoon, the silicone is exactly what you want.

This sits among the tunnel plugs — the ones with a hollow centre that reduce weight without losing width. We've scored and ranked the category, and this one lands in the middle of the pack: well-reviewed, body-safe, and priced higher than some comparable options.

So should you actually buy it?

Yes, if you're past the beginner stage and you want a plug that feels full without feeling intrusive. The platinum silicone is genuinely excellent, the shape avoids the pressure points that make other plugs uncomfortable, and reviewers who've owned it for years still reach for it.

The insertion difficulty is real — this is not the plug you grab when you're in a hurry. But once it's in, it does exactly what it promises: sits comfortably, feels substantial, and doesn't make itself a problem. If that's what you're after, and you're willing to take your time getting it there, it's a solid choice.
