What are inflatable sex toys?
Inflatable sex toys, from an inflatable dildo to an inflatable butt plug or vibrator, have a part that fills with air, or swells, once it's inside you. Other names include expanding, pump-up and blow-up dildos, and inflatable anal plugs or expanding butt plugs. Of the toys below, three fill by hand pump, button or remote, so you decide how full they get; on two more, bulbs or a shaft swell.
How do inflatable toys work?
Attach the Colt XXXL Pumper's hose and squeeze the bulb; the plug keeps its size once the hose comes off, and a quick air-release button deflates it. On the Auto-Throb, holding the inflation button fills it and letting go stops it; it won't pass its maximum, and a double-click starts its pulsing Auto-Throb pattern (another ends it). The Ergo-Fit's bulb fills from a shaft button or the wireless remote. Once inserted, the Extreme-G's two bulbs swell, and the Lil Swell's shaft swells to 1.75 inches in diameter, up from 1.5.
Types of inflatable sex toys
Inflatable butt plugs
The Anal Fantasy Auto-Throb is super-flexible Elite Silicone and ABS; it inflates, vibrates and recharges over USB. The Colt XXXL Pumper, a pump-up plug, is seamless silicone that flexes with you and inflates evenly. Its suction-cup base works with or without a harness, or on a flat surface. More butt plugs and vibrating butt plugs.
Inflating G-spot vibrators
The Extreme-G pairs a curved silicone shaft with two inflatable bulbs that press and massage your G-spot as they swell, for fullness and targeted pressure together. It's 8.2 inches overall, 5.5 inches insertable. More G-spot vibrators.
Swelling rabbit vibrators
On the Inmi Lil Swell rabbit, a ribbed shaft and its curved, G-spot-seeking head thrust and swell through 5 combined swelling, thrusting and vibrating modes, while a clitoral ear buzzes your clit. It's silicone, 8.75 inches overall, 5 inches insertable. More rabbit vibrators.
Strapless strap-ons with an inflatable bulb
The Ergo-Fit skips the harness: the wearer's Kegel muscles hold its bulb, inflated to a custom fit. Dual motors stimulate wearer and partner at once. Its swirly-textured shaft has a defined head shaped for the prostate and G-spot; the wearer gets a textured clit pad. More couples sex toys.
How to choose an inflatable toy
- Where you want it. Anal play (Auto-Throb, Colt), the G-spot (Extreme-G), G-spot and clit (Lil Swell) or both partners (Ergo-Fit).
- How it changes size. A hand pump (Colt), a held button (Auto-Throb), a button or remote (Ergo-Fit) or a swelling shaft (Lil Swell). The FAQ below lists sizes before and after.
- Vibration. The Auto-Throb, Extreme-G, Lil Swell and Ergo-Fit vibrate; the Colt's listing describes none.
- Hands-free or remote. The Colt keeps its size with the hose off, the Auto-Throb's pulsing pattern runs itself and the Ergo-Fit has a remote.
- Water. The Auto-Throb (splashproof), Extreme-G (IPX5), Lil Swell (IPX6) and Ergo-Fit (IPX5) can go in the shower, never the bath.
- With a partner. The Ergo-Fit stimulates you both; the Colt's suction-cup base works in a harness.
How to use an inflatable butt plug or dildo
- Before each use, check the toy, pump, hose, valve or button for damage.
- Coat the toy and yourself in plenty of water-based lube.
- Insert it slowly, fully deflated.
- Inflate a little at a time (a short press or a squeeze or two), then pause while your body adjusts.
- Any discomfort? Stop, let air out and never force it.
- Partner on the pump or remote? Agree beforehand on a word or signal that means stop; when it's used, stop at once and let the air out.
- Deflate fully (the Colt has an air-release button), ease it out slowly and wash it right away.
Cleaning, care and safety
- Wash after each session with warm water, mild soap and toy cleaner, then pat dry.
- Water limits: rinse the Ergo-Fit but never soak it, and keep the Auto-Throb to the shower.
- Colt: wipe the hose and bulb too, and dry every part before storing.
- Silicone? Use water-based lube, not silicone-based.
- For anal use, pick a flared base. The Colt's listing describes a suction-cup base; the Extreme-G and Lil Swell aren't anal toys.
- One toy for anal and vaginal play? Wash it well every time you switch.
- Won't deflate or come out comfortably? Don't pull or force it: get medical help.
- Pain or bleeding means stop. If either carries on, talk to your doctor.
Inflatable sex toy FAQ
What is an inflatable butt plug?
It's a butt plug that fills with air once it's inside you, so it goes in smaller and widens to the fullness you want. The Colt XXXL Pumper fills from a squeeze bulb, the Auto-Throb from a button.
Are inflatable butt plugs safe?
Yes, when you take it slowly. Be generous with water-based lube, add air gradually, let some out at any discomfort and deflate fully before removal. Never force anything. Bleeding, or pain that won't ease? Talk to your doctor.
Can an inflatable butt plug get stuck?
It can be hard to get out while inflated, so always deflate it fully before removal. Check the valve, hose or button before each use. If it won't deflate or won't come out comfortably, don't pull or force it: get medical help.
Can you use an inflatable butt plug to stretch?
Yes: some people use one to explore fullness at their own pace and work up in size gradually. Add air only when the last size feels easy. Bodies differ, so there's no timeline. Prefer set sizes? See anal training kits.
Do inflatable sex toys vibrate?
Many do. The Auto-Throb has 3+7 vibration modes, the Extreme-G 3 speeds and 7 patterns, the Ergo-Fit 3 intensities and 7 patterns, and the Lil Swell's clitoral ear 3 speeds and 4 patterns. The Colt's listing describes no vibration.
How big do inflatable dildos and plugs get?
Sizes vary by toy. Inflated, the Auto-Throb reaches roughly 2 inches across (from just over an inch), the Extreme-G 2 inches (from 1.6) and the Ergo-Fit's bulb 2 inches (from 1.5). The Lil Swell's shaft swells to 1.75 inches across, up from 1.5. The Colt is 6.25 by 1.75 inches before inflation.
What's the best lube for inflatable toys?
Water-based lube, applied generously. The Extreme-G, Lil Swell and Ergo-Fit listings ask for it, and the Extreme-G's says to skip silicone-based lube, which can damage silicone toys. Water-based works with all toy materials. Reapply as soon as anything feels dry.
