The testicles are objectively the most dreaded area of any man's intimate grooming routine. The skin that folds, moves, and holds surprises... and the razor waiting for the slightest mistake. In 2026, this hassle will no longer have any reason to exist. With the right trimmer and the right technique, shaving your testicles becomes a simple, quick, and stress-free act. We'll explain everything, without beating around the bush.
Why testicles are the most delicate area to shave
Unique skin of its kind
The skin of the scrotum is nothing like the rest of the body. It is significantly thinner, very wrinkled, and constantly in motion depending on temperature and activity. This combination makes it the most complex area to maintain: the surface is never really flat, and folds can easily trap a blade or hide stubborn hairs.
Add to that a high density of nerve endings, and you'll understand why the slightest irritation in this area is felt much more than elsewhere. This is not an area to improvise.
The real danger of a razor on this area
A classic razor is designed for relatively flat surfaces accustomed to friction, such as the face or legs. On the testicles, the blade comes into direct contact with ultra-thin and constantly moving skin. The result: high risks of cuts, almost systematic irritation, and practically unavoidable ingrown hairs upon regrowth.
It's not a matter of technique. It's a matter of an unsuitable tool. A bladed razor has no place on the balls, regardless of your experience level. Period.
Hair clipper, beard trimmer, or intimate trimmer: it changes everything
Why classic trimmers should be banned from this area
This is the most common mistake: grabbing the hair clipper or beard trimmer lying around in the bathroom and using it on the testicles. It's understandable, but it's a bad idea. A hair clipper is designed for thick, taut skin, with blades that pass close to the surface without specific protection for sensitive areas. On the thin, wrinkled skin of the scrotum, this guarantees pulling, irritation, or even "big" cuts.
Why? Because the blades of "normal" trimmers are designed to let a maximum of hair through and cut them as quickly as possible. However, this configuration leaves enough space between each guide to allow a piece (or even a large piece) of testicular skin to pass through. And if the skin passes this last protection, it's a disaster! The blade passes and creates a cut; the more skin that passes, the larger the cut will be.
The blade's geometry is also a problem. These trimmers are designed for linear passes on relatively stable surfaces. The balls, however, move, shift, and wrinkle. Using a beard trimmer or hair clipper on your testicles is playing with fire. Even "multizone" body trimmers marketed as versatile are not specifically adapted to this particular area. If you want to know more about the differences between these devices, we covered it in our 2026 men's body trimmer guide.
Why an intimate trimmer changes the game
A trimmer specifically designed for intimate areas like the billy is based on a completely different philosophy. The anti-cut ceramic blade is designed never to come into aggressive contact with the skin, even without a guard. The design prevents thin skin from slipping between the blade teeth, which eliminates the main risk of cuts in this area.
The compact and ergonomic format also allows for easy maneuvering in corners and folds without forcing. And the integrated LED illuminates exactly where you need it, because let's be honest: some areas of the testicles are particularly difficult to see properly. You can discover the billy directly on the product page.
"I often cut myself with a normal trimmer, so the first time I used the billy, I was a bit stressed, but 0 cuts and it was super fast! I'm keeping my billy, 100%!"

Proper preparation before trimming
Dry or in the shower: choose according to your priorities
Both options work very well with a waterproof intimate trimmer like the billy. But they don't give exactly the same result, and it's useful to know that before starting.
In the shower, the skin is more supple, the hairs are damp and slightly softened, and cleaning happens naturally as you go. This is the ideal option if you want to go fast and accept that there might be a few isolated hairs left. Humidity makes some hairs less well-defined and can complicate an ultra-precise pass.
Dry, visibility is better, hairs stand up straight, and the blade works more precisely. If you want a really clean result, with no missed spots, this is the method to prefer. You can then rinse with cold water once the session is over. We also detail all this in our article on irritation-free intimate shaving.
What guard length to choose
For the first time, start with a 6 or 9 mm guard. This is the most comfortable length to get used to the area and handling the trimmer. Once you're comfortable, you can go down to 3 mm depending on the desired result. Guard-free trimming (0 mm) is possible with the billy thanks to its anti-cut blade, but it requires a little more attention and controlled movements. We'll come back to this in the next section.
Technique: how to shave your testicles with a trimmer
The position that makes everything easier
Position is 50% of the result. Standing with one leg elevated on the edge of the bathtub or toilet works very well. Sitting on the edge of a chair, legs slightly spread, is another comfortable option. The goal is simple: to have unobstructed access to the entire area, without contorting your arm into impossible angles. Good lighting, with the help of the billy's LED, and you're ready.
The basic rules: parallel, no pressure, no rushing
Now for the technique. Four rules to keep in mind, and they are all equally important.
Keep the blade perfectly parallel to the skin. This is the number one mistake: tilting the trimmer head and pointing the cutting edge towards the skin. The blade should glide flat, never at an angle. If you feel resistance, it means the angle is not right, not that you need to press harder.
Don't press. The trimmer does the work on its own. Just place it against the skin and slide it, without any pressure. The more you press, the more you unnecessarily increase the risk of an accident. A light touch is your best protection.
Take your time. The testicles do not forgive rushing. The skin can be pulled and pinched if you go too fast and too hard. This is not a cut per se, but it is painful and can leave a mark. Two extra minutes won't change your schedule, but they will change everything about the result.
The direction of trimming, on the other hand, has no particular importance with an intimate trimmer. Unlike a razor where you have to follow the direction of hair growth to avoid irritation, you can go in any direction that suits you best to reach different areas.
Stretching the skin, the gesture that changes everything
This is the most important and most underestimated gesture. With your free hand, gently stretch the skin of the area you are trimming. A relaxed scrotum is a wrinkled surface, difficult to treat uniformly. Stretched, the blade glides well, the cut is clean, and the risk of getting caught in a fold almost completely disappears.
Proceed in sections: stretch one part, trim, then gently move your hand to access the next area. It's methodical, but it's the right way to do it. The billy's LED is really useful here to check that no hairs have been missed in the corners.
"It's really great and tested in real life: no problems! I tested it with and without the guard but especially in the shower and it's really practical, thanks to the little LED!"

Classic mistakes to absolutely avoid
Using a hair clipper or beard trimmer on the testicles, as we've seen, is the first mistake never to make. But there are others, less obvious.
Pressing the trimmer to "go faster" is a common mistake. The sensation of resistance you perceive does not come from insufficient power, it comes from improper blade parallelism. The solution is to adjust the angle, not to press harder.
Neglecting skin tension is a mistake almost all beginners make. We tend to want to do it quickly, by passing the trimmer over relaxed skin. The result is poorly trimmed areas, repeated passes in the same spot, and ultimately more risk than by taking the 30 seconds needed to properly stretch with each pass.
Switching from a classic body tool to the intimate area without cleaning in between is also to be avoided for basic hygiene reasons. And finally: neglecting the LED. It's not there just for show. Use it, especially for the lower areas that you see less well, and you'll be surprised by the hairs you would have missed otherwise. If you want to go further on common male intimate shaving mistakes, our men's intimate razor guide details several of them.
"At Team billy, we often repeat the same thing: technique is 90% of the result. A good trimmer in the wrong hand doesn't achieve much. But with the right movements, even a complete beginner can do it perfectly from the first session."
Philippe, co-founder of billy
After trimming: nothing mandatory, but a few options
Good news: with an intimate trimmer that cuts above the skin without ever coming into aggressive contact with the epidermis, no essential post-trimming care is needed. No need for systematic soothing cream or aftershave product. If the session went well, you rinse, dry, and you're done.
Optionally, if you have sensitive skin or want to pamper the area a bit, a few drops of jojoba oil or pure aloe vera can soothe minor, temporary feelings of warmth. Loose cotton clothing for the first few hours after trimming is also a good idea to avoid friction. But again, with a well-designed trimmer and the right technique, these minor discomforts are rare and temporary. Maintaining your blade also matters: we recommend replacing the ceramic blade every 3 to 6 months to maintain a perfect cut with each session.
FAQ
Can you shave your testicles with a beard trimmer?
No. A beard trimmer is designed for facial skin, which is thicker and flatter. On the thin, wrinkled skin of the testicles, it significantly increases the risk of pulling, irritation, and cuts. A trimmer specifically designed for intimate areas is essential.
Do you need to shave in a particular direction with an intimate trimmer?
No. Unlike a razor, the direction of trimming does not matter with an intimate trimmer. You can go in any direction that suits you to access different areas.
Is it better to shave your testicles in the shower or dry?
Both options work. In the shower, it's faster and more pleasant, but you might miss a few hairs. Dry, precision is better if you want a really clean result. Choose according to your priorities at the moment.
Does shaving your testicles hurt with a trimmer?
No, with an anti-cut intimate trimmer like the billy and the correct technique (parallel blade, no pressure, taut skin), the session is painless. Discomfort almost always comes from an unsuitable tool or poor technique.
How often should you shave your testicles?
It all depends on your regrowth rate and the desired result. Generally, a trim every 1 to 2 weeks is enough to maintain a short, neat length. The advantage of a trimmer is that you don't need to wait for minimal regrowth; you can do it whenever you want.
Is there a risk of cutting your testicles with an intimate trimmer?
The risk is very low with a dedicated trimmer and the correct technique. The billy's ceramic blade is designed not to come into aggressive contact with the skin. Accidents usually only occur with excessive pressure or an improperly adjusted angle, two mistakes that are easy to avoid with a little attention.
Should you use a guard to shave your testicles?
To start, yes, it's more reassuring and gives very good results. The 3 or 6 mm guard is ideal for beginners. Guard-free trimming is possible with the billy's anti-cut blade, but it requires a bit more mastery of movement, especially to keep the blade perfectly parallel to the skin.
