Lelo Loki Wave - Obsidian black

What Is the LELO Loki Wave Prostate Massager?

The LELO Loki Wave prostate massager is a dual-stimulation device designed to provide simultaneous internal prostate stimulation and external perineal stimulation. It sits in a category of personal wellness products that many men are increasingly curious about — and for good reason. Research into prostate health and sexual wellbeing continues to grow, and devices like this one are now widely discussed in the context of male pelvic health. If you're exploring options for sexual health and wellbeing, you might also find our condoms and sexual health collection a useful resource alongside this product.

Priced at £188.99, the Loki Wave Obsidian Black is crafted from body-safe, phthalate-free silicone. It's rechargeable via USB and offers multiple vibration and motion settings. The obsidian black colourway gives it a sleek, discreet aesthetic — though it's the engineering inside that really sets it apart from simpler devices on the market.

How Does the LELO Loki Wave Work?

The defining feature of this device is LELO's WaveMotion technology. Rather than relying solely on vibration, the insertable arm physically moves in a rhythmic, come-hither motion — mimicking the kind of manual stimulation often associated with prostate massage. Here's how it functions in practice:

• The curved insertable arm is positioned to reach the prostate gland, located a few centimetres inside the rectum towards the front of the body.
• The WaveMotion mechanism causes the tip of the arm to move back and forth, applying targeted pressure to the prostate.
• Simultaneously, the external perineal arm rests against the perineum — the area between the scrotum and anus — delivering vibration to this sensitive external zone.
• Eight vibration modes and two independent motors allow you to customise the experience to your comfort level.

The prostate gland plays a role in producing seminal fluid, and it contains a high concentration of nerve endings. Stimulation of this gland is associated with intense sensation for many men, which is why prostate massagers have become a recognised category of sexual wellness device.

Who Should Consider Using the LELO Loki Wave?

This device is intended for adult use by individuals with a prostate. It's suitable for solo use or use with a partner, and it's designed for those who are new to prostate stimulation as well as those with more experience — the multiple settings allow you to start gently and build up gradually.

• Adults with a prostate who are curious about prostate stimulation for the first time.
• Those who have tried vibration-only prostate devices and want to explore motion-based stimulation.
• Individuals looking for a body-safe, rechargeable device from a reputable brand.
• Couples wishing to incorporate prostate play into their shared intimacy.

If you have a diagnosed prostate condition — such as prostatitis, benign prostatic hyperplasia (BPH), or prostate cancer — please speak to your GP before using any internal prostate device. This is important to ensure stimulation is appropriate for your individual health situation.

Is the LELO Loki Wave Suitable for Sensitive Skin?

The silicone used in the LELO Loki Wave prostate massager is non-porous, hypoallergenic, and free from latex, BPA, and phthalates — making it a sound choice for those with sensitive skin or latex sensitivities. Always pair it with a water-based lubricant; silicone-based lubricants can break down the surface of silicone toys over time, which may cause irritation. If you experience any skin reaction, discontinue use and consult a healthcare professional. For general skin health support, our skin care collection includes a range of products that may help manage minor irritation.

Store the device in its included satin storage pouch, away from direct sunlight and extreme temperatures. Charge fully before first use and ensure the device is completely dry before recharging to avoid damage.

This product is a personal wellness device, not a medicine. However, if you have an underlying medical condition affecting the prostate or pelvic region, speak to your doctor or pharmacist before using.

What Is the LELO Loki Wave and What Is It Used For?

The LELO Loki Wave Obsidian Black is a rechargeable, dual-stimulation prostate massager designed for adult personal use. It is used to provide internal prostate stimulation via a WaveMotion arm and simultaneous external perineal stimulation via a secondary vibrating arm. It is not a medical device and is not intended to diagnose, treat, or cure any medical condition. Its primary purpose is sexual wellness and pleasure for individuals with a prostate.

Prostate health is an important aspect of male wellbeing. The NHS notes that the prostate gland can be affected by a range of conditions as men age, and maintaining awareness of prostate health is encouraged. This device is a consumer wellness product — it is not a substitute for medical prostate examination or treatment. If you have concerns about your prostate health, always speak to your GP.

What Do You Need to Know Before Using the LELO Loki Wave?

Before using this device, please read the following carefully. There are situations where use may not be appropriate without medical advice first.

Do not use this device if you:

• Have been diagnosed with prostatitis, prostate cancer, or any active prostate condition without first consulting your GP.
• Have had recent rectal or pelvic surgery — allow full healing and seek medical clearance.
• Have haemorrhoids or anal fissures that are currently symptomatic — insertion may worsen discomfort.
• Are allergic to silicone or any material used in the device's construction.
• Are under 18 years of age.

Important warnings:

• Always use a generous amount of water-based lubricant before insertion — never use the device dry.
• Do not use silicone-based or oil-based lubricants, as these degrade the silicone surface.
• Never use a damaged device — inspect before each use.
• Do not share this device with others without thorough cleaning and use of a condom over the device.
• Keep out of reach of children.

Interactions:

• This is not a medicine and has no known drug interactions.
• If you are taking anticoagulant medicines (blood thinners) and experience any rectal bleeding, seek medical advice promptly.

How Should You Use the LELO Loki Wave?

Using the LELO Loki Wave correctly is important for both comfort and safety. Take your time, especially if this is your first experience with a prostate massager. Rushing can cause discomfort or injury.

1. Charge the device fully before first use using the included USB charger.
2. Clean the device thoroughly with warm water and mild soap or a dedicated toy cleaner.
3. Apply a generous amount of water-based lubricant to the insertable arm and to the anal opening.
4. Find a comfortable position — lying on your back with knees bent, or on your side, are common starting positions.
5. Gently insert the curved arm, allowing your body to relax and guide the device naturally — never force it.
6. Position the external perineal arm against the perineum.
7. Press the power button to turn on the device and use the controls to cycle through vibration and WaveMotion settings.
8. Start on the lowest setting and increase gradually as you become comfortable.
9. After use, power off the device, remove gently, and clean immediately.

What Are the Possible Side Effects of the LELO Loki Wave?

This is a consumer wellness device, not a medicine. However, as with any internal device, some individuals may experience discomfort or adverse reactions. If you experience persistent pain, bleeding, or signs of infection, stop use immediately and seek medical advice. You can find further support through our pain relief collection if you experience minor localised discomfort after use.

Common experiences (usually mild and temporary):

• Mild localised pressure or fullness during use.
• Temporary sensitivity in the perineal area after use.
• Minor muscle fatigue in the pelvic floor region.

Less common — seek advice if these occur:

• Skin irritation or redness around the anal area — may indicate sensitivity to lubricant or device material.
• Discomfort lasting more than a few hours after use.
• Any rectal bleeding — stop use immediately and contact your GP.
• Signs of infection (unusual discharge, fever, increasing pain) — seek prompt medical attention.

How Should You Store the LELO Loki Wave?

Proper storage keeps the device hygienic and extends its lifespan. Follow these guidelines:

• Store in the included satin storage pouch to protect the silicone surface from dust and lint.
• Keep in a cool, dry place away from direct sunlight and heat sources.
• Do not store near sharp objects that could puncture or scratch the silicone.
• Ensure the device is fully dry before storing, particularly around the charging port.
• Do not store with silicone-based products, as prolonged contact may affect the surface.
• Charge every few months if not in regular use to maintain battery health.

For broader sexual health and wellbeing support, our personal lubricants collection includes water-based options that are fully compatible with silicone devices like the LELO Loki Wave.
