The cockring, or penis ring, is an intimate toy designed to encircle the base of the penis and, depending on the model, the testicles. It works on a simple physiological principle: it applies moderate pressure that slows venous return without impeding arterial blood flow.


Beyond physical performance, the cock ring heightens sensitivity. The increased blood engorgement makes the penis more responsive to stimulation. For couples, it is a valuable ally that helps prolong intercourse by delaying ejaculation through gentle compression of the urethra.


With this in mind, ONY, the French brand of intimate accessories for men, has created Pulse One, a cockring specifically designed to prolong erection and intensify sensations.


These pleasure-focused products are designed as tools for personal fulfilment, combining ergonomics and effectiveness to help men rediscover their erectile potential while exploring new heights of pleasure.

Key takeaways from the article

This article was produced by ONY, the first French brand specialising in intimate accessories for men.

A cockring slows venous return without blocking arterial blood flow, allowing you to achieve a firmer, fuller and longer-lasting erection.

For safe placement, apply water-based lubricant generously, place your cockring on a semi-erect penis and never wear it for more than 20–30 consecutive minutes. 

Always check that the ring is comfortable: if your glans turns pale blue or feels cold, remove it immediately.

Choosing the right cockring: a guide to types, sizes and materials

Pulse One

The choice of cock ring determines comfort, safety and the quality of the experience. It is essential to understand the technical criteria in order to distinguish a quality accessory. The first factor is the intended use: are you looking for erection support, vibrating stimulation or a sensation of restraint?

Rigidity is a crucial factor. You should opt for flexible materials to get used to the constriction. Using rigid models (metal) carries risks. Width also plays a role: a wide ring distributes pressure over a larger area and often provides greater comfort for extended wear.

The different types of cockrings and their features

The market offers three main families of rings. Simple rings, often made from silicone, focus on maintaining erection through constriction. Double or "full package" models feature two loops: one for the shaft and one for the testicles, providing a stretching sensation and delaying ejaculation more effectively.

High-tech rings incorporate motors to stimulate erogenous zones. This is where innovation truly stands out. Vibrating cockrings such as the Pulse One by ONY offer different vibration modes. They don't simply maintain an erection; they transform the accessory into a genuine sex toy for couples, stimulating the clitoris or perineum through varied frequencies.

Size and material: the keys to a successful choice

Size is the number one safety factor. A ring that is too tight can cut off circulation (tourniquet effect), while a model that is too loose will be ineffective. For a first purchase, opt for a stretchy model.


The material is vital for hygiene and comfort. Avoid porous materials that harbour bacteria at all costs. ONY emphasises the importance of premium, soft and body-safe materials, such as the premium silicone used in Pulse One by ONY. This silicone is hypoallergenic, non-porous and offers a velvety feel ("Soft Touch") that protects sensitive skin while ensuring outstanding durability.

How to put on a cockring: your step-by-step guide

Putting on a cockring may seem daunting, but it is a simple process with the right technique. The key lies in patience and listening to your body. Never force it. If you feel any pain, the model is not suitable or the preparation is insufficient.


Choose a calm moment and a comfortable temperature to encourage relaxation. Have everything you need to hand: your clean cock ring and a suitable lubricant.

The golden rule for using a cockring is to never attempt to put it on when fully erect (100%), especially with rigid materials. The volume of the penis would make insertion painful. The ideal state is a semi-erection, where the penis has increased in volume but remains sufficiently flexible.


Here are the steps for safe placement:

Preparation and lubrication: the basics of successful placement

Lubrication is an absolute necessity to avoid any irritation. Apply lubricant generously to the base of the penis, to the testicles (if using a double model) and to the inside of the ring.

A note on product choice: if your ring is made from silicone, such as those in the ONY range, you must use a water-based lubricant. Silicone-based or oil-based lubricants can irreversibly degrade the material, making it porous.

Placement techniques: penis only or with testicles included

For a simple ring (around the shaft only):

  1. Bring your penis to a semi-erect state (50 to 70% firmness).

  2. Gently stretch the ring with your fingers.

  3. Slide the accessory over the glans, then move it down along the shaft to the base, against the pubis.

  4. Release the ring and adjust it until it feels comfortable.

To include the testicles: first pass one testicle through the ring, then the second, and finally slide the penis through. This method avoids trapping the scrotal skin.

Bonus: our tips for optimal comfort and a perfect fit

Once the ring is in place, check the colour of your glans. It should become darker (red or purple) due to increased blood flow, but it should never become cold, pale blue or white — a sign that circulation has been cut off.

For comfort, consider trimming the hair at the base of the penis to prevent it from getting caught in the silicone or metal. Finally, if the ring slips too much, it is too large; if it pinches your skin, it is too small.

Maximise your experience safely

Putting on a cockring goes beyond a simple mechanical improvement; it opens the door to new sensations. Once in place, you will notice increased sensitivity in the glans and significant engorgement. This is the perfect moment to vary the pace and focus more on your partner's pleasure and the emotional connection.

Vibrating cockrings: multiply your sensations

Vibrating models add an extra dimension. Positioned correctly, the upper vibrating module will stimulate your partner's clitoris during penetration. This dual stimulation synchronises pleasure and encourages mutual orgasm.

Essential precautions and recommended wear time

Safety is paramount. The absolute rule is to never wear a cockring for more than 20 to 30 consecutive minutes. Beyond that, lack of tissue oxygenation (hypoxia) can cause damage.


If you feel any pain, numbness or a cold sensation, remove it immediately. Use plenty of lubricant or soapy water to help with removal. Never fall asleep wearing a cock ring.

Your questions about cockrings: expert answers

Why wear a ring around the testicles?

Wearing a "full package" ring (shaft and testicles) offers several advantages. Firstly, it prevents the testicles from drawing up during orgasm, which delays ejaculation more effectively than a standard ring. Secondly, the stretching sensation of the scrotum provides constant stimulation. Finally, visually, it projects everything forward, which can be highly arousing and boost confidence.

Vibrating cockrings: are there any side effects?

Vibrating cockrings are safe when used correctly. Side effects (bruising, oedema) are linked to improper use: wearing for too long (>30 min) or too tight. The vibrations themselves are not dangerous, but excessive intensity may cause temporary desensitisation. It is advisable to vary the modes and take breaks to preserve nerve receptivity.

How long can you safely wear a cockring?

The maximum recommended duration is 20 to 30 minutes per session. It is essential to respect this limit to allow oxygenated blood to circulate freely through the tissues again. If you wish to use it several times, allow yourself a break of at least 60 minutes between sessions. Comfort always comes first: remove the accessory at the first sign of discomfort or pain.
