Humblers, ball crushers and ball weights: a practical CBT guide

Once a simple ball stretcher feels familiar, many men want gear that does more than pull: a bar that keeps them on their knees, plates that press, weights that swing. That is cock and ball torture, CBT for short. This guide covers humblers, ball crushers (often searched as "penis crusher"), parachutes and ball weights, magnetic ball stretchers and bull bags: how each works, how to fit it, how long to wear it and when it comes off right now. For measuring and a first ring, read the ball stretcher guide first; the basic rings are in ball stretchers and weights.

Before you start: consent, safewords and limits

CBT is for consenting adults only. Talk before the scene: what is in, what is off limits, how long, who holds the keys. Agree on a safeword and on a signal without words, such as three taps, because a man in a humbler with a gag in may not be able to speak. The wearer can end the scene at any moment.

Keep everything for a fast release within reach: Allen key, padlock keys, scissors for straps. Never play drunk or high, and never leave someone alone in a locked device. With a hernia, a varicocele, circulation or nerve problems, or recent surgery in the area, ask a doctor first.

Humblers: the humbler ball stretcher explained

A humbler is a bar, usually of wood, that closes around the neck of the scrotum and rests against the back of the thighs, just below the buttocks. As soon as the wearer tries to straighten his legs, the bar pulls his balls backwards, so he stays on his knees or bent forward. The position does the work, not a weight, which is why it is often called a humbler ball stretcher.

Four kinds of humbler

• Wood with ankle cuffs: the Extreme Humbler with Ankle Restraints closes with knobs and has clasps for padded ankle cuffs that keep the knees bent. The buckles take locks, which are not included.
• Spiked: the Thorns Spiked Wooden Humbler is beechwood with rows of flat tipped spikes facing the skin, tightened with knobs. The slot measures about 64 by 19 mm.
• E-stim: the Exposed E-Stim Wooden Humbler has contact points for standard 4 mm leads and a lock with two keys; the slot is about 43 by 18 mm. It needs a separate power unit from electro stimulation. Use only units made for erotic play and never run current above the waist.
• Steel: The Ultimate Humbler is lockable stainless steel with an adjustable stretching ring, a press plate with a flat and a spiked side, and attachment points for ankle or wrist cuffs.

How to fit a humbler

The opening is a slot, not a ring, so compare the slot on the product page with the width of your scrotum just above the testicles, measured warm and relaxed. The wearer kneels, the balls are guided back between the thighs, and the bar is closed above the testicles. Tighten until the balls cannot slip back through, then stop: a fingertip should still slide along the skin inside the slot. Check for trapped hair and folded skin. Start with 10 to 15 minutes, kneeling rather than bent forward.

Ball crushers and presses

A ball crusher, also called a ball press and often searched for as a penis crusher, squeezes the testicles between plates or shells that you tighten with screws. The stimulus is pressure, and whoever holds the key sets it. The Evil Ball Crusher and Presser holds each testicle in its own shell, with 13 screws per side, an Allen key, thumbscrews and two padlocks. Without the screws it works as a plain stretcher.

• Start with every screw loose and tighten in quarter turns, pausing after each one.
• Pressure is felt late. If pain keeps building a minute after the last turn, loosen.
• Work in short rounds: a few minutes of pressure, then release fully.
• A dull ache spreading into the lower belly, nausea or sudden sharp pain means open everything at once.

Parachutes and ball weights

A parachute is a collar of leather or steel around the scrotum with chains that meet below it at a hook, where the weight hangs. The weight swings, so every movement adds pull. The Oppressor's Orb is a stainless steel ball weight with a connection point, so you can clip it to a parachute, ring or chain and hang more weight below it. The Ball Trap is a metal ring with a 33 mm inner diameter, closed with screws, with two attachment points for weights or a chain to ankle cuffs.

Add weight in small steps, and only once the ring alone is comfortable for an hour. Standing and walking make the same weight pull much harder than lying down, and a weight should never drop or jerk.

Magnetic ball stretchers: how the closure works

A magnetic ball stretcher has two halves, or a ring with a removable wedge, with strong magnets set into the steel. You place the halves around the neck of the scrotum and they snap together: no screws, no squeezing your balls through a closed ring, and off in seconds.

• Steel Triad Magnetic Ball Stretchers: three stackable rings, 36 mm inner diameter, 7.8 cm high and about 411 g together. Start with one ring.
• Magna-Chute: a bell shaped steel parachute with a 31 mm inner diameter and a magnetic closure.
• Magnet Master XL: a long, heavy two part stretcher for men who already wear height comfortably.

Stacking adds height and weight, and height pulls as much as weight does, so add one ring at a time. Magnets snap hard: close the halves slowly and check that no skin is caught. Keep them away from pacemakers and implanted devices, bank cards and phones, and skip impact play on them, because a hard knock can push the halves open.

Bull bags

A bull bag is a stretchy rubber sleeve that encloses the whole scrotum, with weight at the bottom. You stretch the opening and ease it down over the balls, no buckles. The PerfectFitBrand Bull Bag in black is the snug size. Use water based lube only. An opaque bag hides the colour of the skin, so check warmth and feeling every ten minutes.

Which device for which goal

Lengthen a session only when the previous one left no soreness the next day.

Warning signs: take it off at once

Check every ten minutes: colour, warmth with the back of the hand, and feeling. Remove the device immediately at:

• skin that turns cold
• blue, purple or very dark skin
• numbness or pins and needles
• sharp pain, or pain spreading into the belly
• swelling that keeps growing

A short tingle as the blood returns is normal; pain that stays is not. Never sleep in any of this gear. If a device will not come off, or symptoms remain after removal, seek medical help without delay.

Playing with a partner

In a humbler the wearer cannot see his own balls, so the partner watches colour and checks in. Keep the keys in the room. When you combine restrictions, the shortest safe time counts: a humbler with ankle cuffs and a weight on the ring is more than the sum of its parts. Many men add a soft silicone cock ring such as The Cog; fit is covered in the cock ring guide. Combinations are under cock and ball toys, softer stretchers under ball straps.

Cleaning by material

• Stainless steel: warm water with mild soap or a toy cleaner; dry threads and magnets well.
• Wood: wipe with a damp cloth and toy cleaner, never soak, dry at room temperature. Wood is porous, so keep a humbler to one wearer.
• Leather: wipe clean, treat with leather care, never soak.
• Silicone and rubber: warm water and soap; with rubber, water based lube only.
