Sex machines: how to choose your first fuck machine

A sex machine does one thing a partner cannot: it keeps going at exactly the pace you set, for as long as you want. Some men buy one for solo nights, some for a partner who likes to watch or hold the remote, and some because their arm gives up long before their ass does. The differences between models are bigger than the photos suggest. This guide explains what to look at, which type suits you and how to use one safely.

How a sex machine works

A motor drives a rod back and forth, and a dildo sits on the end of that rod. Three numbers decide how it feels:

• Stroke length: how far the dildo travels on each thrust. A stroke of 5 or 6 cm feels like quick, shallow pumping; 9 cm or more feels like being properly fucked. The better machines let you set it.
• Speed: listed as strokes, thrusts or rotations per minute. Around 200 per minute is already fast; the top machines reach 280 to 300.
• Angle and height: how far you can tilt and raise the arm. That decides which positions work: on your back, on all fours, sitting on it or strapped to a bench.

The main types compared

Milking machines are a family of their own; you find them with the automatic masturbators. The rest of this guide is about thrusting machines.

Hand-held: the cheapest way to find out

Never used a machine? Start here. The Ouch! Hand Held Vibrating and Thrusting Sex Machine combines thrusting and vibration with 13 speed modes, is rechargeable and splashproof, and costs less than a good dildo. The XR Brands Jaxxx Hammer 2.0 sits on a swivelling suction cup base or comes off it for hand-held use, with three thrusting speeds and a veined dildo of about 15 cm insertable and 3.8 cm wide. The Thrust-Bot is built like a power tool with a trigger and a safety switch, runs on a rechargeable battery pack and takes Vac-U-Lock dildos through the included adapter. The catch with every hand-held model: somebody has to hold it, or it needs a smooth surface to stick to, and the stroke is shorter than on a floor machine.

Floor machines: the sweet spot

A floor machine stands on its own, so you can lie back and let it work. The Shots Sexmachine is light and compact, with an aluminium arm, twist knobs for angle and height, four suction cup feet, a speed remote, and both a bendable dildo and a stroker sleeve in the box. The XR Brands Deluxe Pro-Bang has 4 speeds and 7 thrusting patterns at up to 285 strokes per minute, an 8.9 cm stroke, a remote with a range of almost 10 metres and a Vac-U-Lock adapter for your own dildos. The Doc Johnson Power Banger runs from a slow 28 to 195 strokes per minute, holds with four suction cups and fits every Vac-U-Lock toy, the Signature Cocks included. The LoveBotz Robo Fuk Deluxe tilts across 135 degrees and is light enough to take away for a weekend.

Heavy-duty machines: for the long run

Once you know machine play is for you, a serious machine adds stability, an adjustable stroke and a motor that does not slow down under load. The F-Machine Pro 4 reaches 280 rpm, lets you set the thrust depth from 2.5 to 15 cm, stands on weighted steel legs with quick-release clamps, and comes with an 8 inch silicone dildo and a Vac-U-Lock style adapter. The F-Machine Alpha changes its depth while it runs, from 25 to 133 mm, and is controlled over Bluetooth with the F-Machine Connect app, by you or by a partner anywhere in the world. The Lovense Sex Machine is app controlled as well, reaches 300 strokes per minute and adjusts stroke, angle and height. For double penetration the XR Brands Athens drives two rods at once, and the XR Brands Axis tilts across 45 degrees at up to 250 thrusts per minute.

Machines built into furniture

A bench or a bondage frame puts your body at the right height and keeps it there. The Deluxe Bangin' Bench is a steel bench for up to 100 kg with a machine that clamps onto the frame and thrusts up to 195 times a minute; without the machine it is a riding bench for you and a partner. The Subversion Deluxe Stockade holds a man face down with ten straps and an angled hip cushion, with the machine behind him. More benches, slings and frames are in slings and furniture.

Dildos and the Vac-U-Lock system

Most machines come with one dildo, and it is rarely the one you end up using most. Check how the toy attaches. Many machines use Doc Johnson's Vac-U-Lock, or include an adapter for it: a plug on the machine that slots into a hollow base on the dildo. With it you can run dildos you already own, as long as the base has the Vac-U-Lock opening. F-Machine uses its own fitting and sells adapters, such as the Hung Adapter for heavy Hung System toys. Start with a dildo smaller than your favourite manual one: a machine does not get tired, and twenty minutes of steady thrusting is a lot more than twenty minutes by hand. Good shapes are in realistic dildos; for the big ones, read the XXL dildo guide first.

Power, noise and space

• Mains or battery: battery models are easy to move and store; mains-powered machines keep their full power for hours. Check the plug, because some models ship with a US cord or a separate adapter.
• Noise: every machine makes some sound. A well-built motor hums, cheap gears rattle. If you share walls, a compact machine on a rug is the quiet option.
• Grip: a machine that slides away on every thrust kills the mood. Suction cup feet need a smooth, hard floor; heavy machines stay put on their own. The F-Machine Rocket Stand exists for exactly this.

Your first session

• Douche if you plan to go deep (see how to use an anal shower) and warm up with fingers or a small plug first.
• Set the machine up before you get on it: angle, height and the shortest stroke. Check that the dildo is screwed or locked on tight.
• Use plenty of water-based lube, which is safe with every material, and keep the bottle within reach.
• Position yourself so the tip just touches, then start at the slowest speed. Move your body towards the machine, not the other way round, until you know how deep the stroke goes.
• Keep the remote or the dial in your hand and stop at once if anything hurts. Sharp pain is a signal, not a challenge.
• Never combine a machine with being tied up alone. In a bondage scene the man who is free holds the controls and stays in the room.

Cleaning and care

Unplug the machine first. Wash the dildo with warm water and mild soap or a toy cleaner, wipe the arm and frame with a damp cloth, and never put the motor or the controller under water. Let it dry, and check the screws and the dildo fitting now and then.

Frequently asked questions

Is a sex machine the same as a fuck machine?

Yes. Both names describe a motorised device that moves a dildo in and out. Some brands also use the word for milking machines, which stroke and suck the cock instead.

Which sex machine is best for beginners?

A hand-held thrusting toy, or a compact floor machine with a slow lowest speed and an adjustable angle. You learn which pace and depth you like before you spend on a heavy-duty model.

Can I use my own dildo on a sex machine?

Often, yes. Machines with a Vac-U-Lock plug or adapter take any dildo with a Vac-U-Lock base. Other machines use their own fitting, so check the product page before you order toys for it.

How fast does a sex machine go?

The floor machines we stock reach 195 to 300 strokes per minute at full speed. The lowest setting matters just as much: around 30 strokes per minute is slow enough to start comfortably.

Are sex machines loud?

They are not silent. Compact machines with a good motor hum at a level you can talk over; open gears and cheap motors are louder.
