What is a Funnel Gag?
Funnel Gag: A funnel gag is a mouth gag sex toy with a wide, cone shaped opening attached to a strap or harness, used in kink play to hold the mouth open and sometimes to pour liquids in for humiliation, feeding, or power exchange scenes.
Also known as: Feeding gag, Cone gag.
A funnel gag is a type of mouth gag built around a hollow, cone shaped piece that sits between the lips and teeth, usually attached to head straps or a harness. Unlike gags that just fill the mouth, the funnel gag has an open channel running through it, which is what lets liquid pass through if a couple chooses to use it that way. It shows up most in BDSM and power exchange play, where the visual of an open, exposed mouth and the feeling of being controlled are the main draw.
If you are curious about trying one, you are not alone in feeling a little unsure where to start. This is a toy that asks for more planning and more trust than a lot of other gags, mostly because it can involve liquids and because it takes away your partner's ability to speak clearly. Go slow, talk everything through first, and treat the funnel gag as a tool for a scene you both design together, not something to spring on anyone.
What Is a Funnel Gag Used For
The funnel gag is popular in humiliation play and power exchange dynamics because it makes the mouth the center of attention. The wide opening holds the jaw apart in a way that looks and feels very exposed, which is exactly the point for people who enjoy that dynamic. Some couples use it purely for the visual and the sensation of having the mouth held open, with nothing poured through it at all.
Others use the funnel as an actual channel, most commonly for water, in scenes built around feeding, control, or degradation fantasies. Whatever liquid gets used, it should always be something food safe and agreed on in advance, never anything that could irritate the mouth or throat or that either partner has not consented to. This is a toy where the fantasy and the practical safety planning have to move together, not one after the other.

How to Use a Funnel Gag Safely
Start by fitting the gag with the straps loose, then tighten gradually until it sits snug but not painful against the head. Check that your partner can still breathe easily through the nose, since the mouth will be held open and partly obstructed. Ask for a thumbs up or a nod before you consider the fit finished. A gagged partner cannot say a safe word out loud, so agree on a hand signal, a dropped object, or a series of taps beforehand and confirm both people know it cold.
If liquid is part of the scene, pour slowly and in small amounts, and pause often to let your partner swallow and breathe. Never leave someone alone while wearing a funnel gag, even for a moment. Keep sessions short, especially the first few times, and check in verbally as soon as the gag comes off. Afterward, rinse the gag with warm water and a mild, toy safe cleanser, then let it air dry fully before storing it, since trapped moisture can encourage bacteria to grow on non porous materials.
How to Choose the Right Funnel Gag
Look for gags made from body safe materials like medical grade silicone or rigid, non porous plastic, since these clean easily and will not degrade the way some cheaper materials do over time. Check the diameter of the funnel opening. A wider mouth gives more airflow and a gentler feel, while a narrower one creates a more intense stretch and a slower pour if liquid is used. Adjustable straps or a full harness give you more control over fit than a single fixed strap, especially if more than one person will be wearing the gag.
Pay attention to how the gag attaches at the back, whether it is a buckle, a clip, or a locking mechanism, since you want something you can undo quickly if needed. If you are new to gags in general, a simpler funnel gag with a moderate sized opening and soft padding where it meets the skin is a comfortable place to start.
Is a Funnel Gag Safe to Use
Used thoughtfully, a funnel gag can be a safe addition to a scene, but it does carry more to think about than most gags. The biggest concerns are breathing, gag reflex, and aspiration if liquid is poured too fast or in the wrong position. Never use a funnel gag on someone who is intoxicated, drowsy, or has a cold or congestion that makes nose breathing difficult. Position matters too, keeping the head tilted so liquid can be swallowed comfortably rather than pooling in the throat greatly reduces the risk of choking.
People with jaw problems, TMJ issues, or a strong gag reflex should talk to a doctor before trying any mouth gag, funnel style or otherwise. Watch for signs of distress like frantic tapping, muffled distress sounds, or the agreed safe signal, and remove the gag right away if you see them. Clean the toy thoroughly between uses and between partners, since anything that goes in the mouth needs the same hygiene attention as any other intimate toy.
Talking to Your Partner About Using a Funnel Gag
Because a funnel gag limits speech and sometimes involves liquids, the conversation before the scene matters as much as anything you do during it. Talk through what the gag is for in this particular scene, whether liquid will be involved, what liquid, how much, and how it will be paced. Agree on the non verbal safe signal together and practice it once before you start, so it becomes automatic under pressure.
Discuss limits around how long the gag stays in, what position feels safest, and what aftercare looks like once it comes off, since jaw soreness and a dry mouth are common afterward. Checking in the next day about how it felt, physically and emotionally, helps you both figure out what to adjust next time.
Funnel Gag vs Ball Gag: Quick Comparison
| Funnel Gag | Ball Gag | |
|---|---|---|
| Shape of opening | Hollow cone, open channel through the middle | Solid sphere, no opening |
| Can liquid pass through | Yes, if the scene includes that | No |
| Airflow | Generally more open around the mouth | Depends on ball size, can feel more filling |
| Main use | Visual exposure, feeding or humiliation scenes | General restraint of speech, classic look |
| Beginner friendly | Moderate, needs more planning if liquid is used | Yes, simpler to use for first timers |
Types of Funnel Gag
Funnel gags come in a few common styles, mostly differing in how the funnel attaches and how the harness holds it in place.
- Harness Funnel Gag: A funnel piece built into a full head harness with adjustable straps for a secure, customizable fit.
- Open Tube Funnel Gag: A simple design with a straight hollow tube through the funnel, favored when liquid play is part of the scene.
- Detachable Funnel Gag: A gag where the funnel piece can be removed from the strap system, making cleaning and swapping funnel sizes easier.
- Padded Funnel Gag: A funnel gag with cushioning where the straps meet the skin, good for longer wear or sensitive skin.

Key Things to Know
- The open channel is what sets it apart, this is what allows liquid play, so decide with your partner in advance whether that is part of your scene or not.
- A non verbal safe signal is essential, since a gagged partner cannot use a spoken safe word, so agree on one before you start.
- Nose breathing has to stay clear, so check the fit and skip this toy entirely if either partner has congestion or breathing trouble that day.
- Body safe, non porous materials like silicone clean more reliably, which matters because anything placed in the mouth needs careful hygiene.
- Short sessions with frequent check ins reduce strain on the jaw and throat, which makes the experience more comfortable for a first time user.
FAQ
What is a funnel gag used for?
A funnel gag is mainly used in BDSM and power exchange scenes to hold the mouth open and create a strong visual of exposure and control. Some couples use it purely for that sensation and look, with nothing passed through the funnel at all. Others incorporate liquid, most often water, as part of feeding or humiliation fantasies that both partners have discussed and agreed to beforehand.
Is a funnel gag safe for beginners?
It can be, but it asks for more preparation than a simple ball gag or bit gag. Beginners should start without any liquid, focus on getting the fit and the non verbal safe signal right, and keep the first sessions short. If nose breathing ever feels restricted or a partner shows signs of distress, remove the gag right away and check in.
Can you choke on a funnel gag?
Choking risk mainly comes into play if liquid is poured too fast or a person is not positioned to swallow comfortably. This is why pacing, small amounts, and constant check ins matter so much when liquid is involved. If you are new to funnel gags, it is safer to leave liquid out of the scene entirely until you both feel confident with the fit and the signals.
How do you clean a funnel gag?
Rinse the gag with warm water right after use, then wash it with a mild, toy safe cleanser, paying attention to the inside of the funnel channel where residue can collect. Let it air dry completely before putting it away, since leftover moisture on non porous materials can allow bacteria to build up. Always follow the manufacturer's specific care instructions, since materials like silicone and rigid plastic can have different cleaning needs.
What is the difference between a funnel gag and a ball gag?
A funnel gag has a hollow, open center that can let liquid pass through, while a ball gag is a solid sphere with no opening. Funnel gags are chosen when a couple wants that open channel for a feeding or humiliation scene, while ball gags are a more general purpose choice for restricting speech. Ball gags also tend to feel more beginner friendly since there is no liquid element to plan around.
Do you need a safe word with a funnel gag?
You need a safe signal, but it cannot be a spoken word since the gag limits speech. Common options include tapping a surface a set number of times, dropping a held object, or using a bell or noisemaker. Whatever you choose, practice it together before the scene starts so it becomes automatic if it is needed.
