FMS dilators for prostate massage offer the following advantages over other products made of silicone or plastic:
There’s no universally correct size for a prostate massage dilator. However, very small dilators often provide too little or even unpleasant stimulation, as the contact area is too small. Our dilators under 14 mm are not designed for prostate massage, but rather for other therapeutic uses. Based on experience, a diameter of at least 24 mm is recommended for effective prostate massage.
A dilator over 24 mm will increase the intensity of the massage, but it will also place more strain on the anal sphincter. That’s why it’s important to find out in advance which size your body can comfortably accommodate, to avoid pain during insertion or over the course of the massage. We provide tips to help you determine the right size for you.
A dilator set allows you to adapt to your body’s capacity and gradually increase the size if you're ready. A set with 24, 28, 32 and 36 mm is a good place to start. Don’t forget to check out our discount scale when purchasing!
In general, take your time and make sure you're relaxed. Erotic arousal can also be very helpful. Warmth helps relax the anal sphincter and has a positive psychological effect as well. To enhance the experience, you can prepare a container with hot water to warm the dilators as needed. A baby food warmer is ideal, as it maintains a constant temperature.
To check the right temperature, briefly hold the dilator against the inside of your thigh. FMS dilators from around 30 mm upwards can also be sustainably pre-warmed using a filling system – you’ll find more information about this in the user manual.
The following items are essential:
The Right Position
You can perform the prostate massage while lying on your side, pulling your top leg up (similar to the recovery position) and inserting the dilator from behind. However, this position limits your range of motion. It’s a good idea to think ahead and keep all necessary equipment within reach.
A seated position with open, bent legs offers the best freedom of movement. Our V-Stool, especially the version with longer legs, is ideal for this purpose. It allows you to guide the dilator either from the front or back, and to alternate between both hands. You can also sit on the stool in a reversed position: this causes the lower body to “hang through” more, gently stretching the body openings.
Insertion
Before starting, apply some lubricant around the anal area and gently massage the anal sphincter with your fingertips to relax it. Then spread a bit of lubricant onto the dilator (after drying it if it was warmed in a water bath), and dry your hands thoroughly.
Now carefully insert the head of the (warmed) dilator – a few centimeters are enough at first – and take a moment to relax.
Types of Massage
Next, slowly insert the dilator deeper – not straight, but at a slight angle toward your belly, in the direction of the prostate, until you feel it. You’ll clearly notice it, as touching the prostate can feel unfamiliar at first if you're not used to it.
By moving the dilator two to three centimeters in and out, you create a tapping or pressure-point massage effect on the prostate, especially on its rear area facing the rectum. Start gently, giving yourself time to get used to the sensation. Even this light massage can strongly stimulate prostate function.
As you gain experience, you can begin massaging the outer areas of the prostate, moving around it. This requires a tilting or wobbling motion: insert the dilator a bit deeper so the head sits slightly beside or behind the prostate, rather than directly in front of it. Then make small circular movements with the end of the dilator. This causes the head to move in the opposite direction around the prostate, creating a more comprehensive massage of the outer tissue. It takes a bit of practice to find the right depth, pressure, and radius – but you’ll get the feel for it over time.
If you feel ready to use a larger dilator, you can increase the size - entirely based on your comfort. A dilator with a diameter of 36 mm creates a stronger effect than one with 24 mm. However, the size should generally not exceed 44 mm, as a dilator that is too large can no longer be guided effectively due to the increased resistance of the surrounding tissue. Stretching is not a relevant factor in prostate massage.
There’s no one-size-fits-all guideline here - people are different, as are their time constraints and the urgency or severity of prostate-related issues.
In general, the following applies:
Try to make the practice as regular as possible. The rule is: more makes more. Establish consistent times instead of leaving it up to chance. If you can manage it, do a short session both in the morning and evening. Otherwise, aim for at least one longer session per day.
Prostate massage can lead to the discharge of prostatic fluid—sometimes accompanied by orgasm or varying levels of sexual arousal, but often without either. This is a completely normal phenomenon. It does not necessarily depend on the intensity of the massage, but can also be influenced by your imagination, psychological factors, and whether the massage is performed by another person.
Prostate massage can also be performed by a partner as a special form of penetration, offering a unique kind of intimate attention. This kind of sexual play - penetration of a man by a woman (often referred to as pegging) - can sometimes help resolve issues such as erectile dysfunction or reduced potency. The experience can activate or reconnect the man with his feminine aspect. For a healthy flow of energy—which is the foundation of healthy sexual function—both poles, masculine and feminine, are needed. This principle is reflected in the ancient Yin-Yang symbol. It applies to all things and to all people, regardless of which gender identity they primarily relate to.
