What Is the LELO Loki Prostate Massager?

The LELO Loki prostate massager in Obsidian Black is a dual-stimulation device designed for prostate and perineum pleasure. Crafted from body-safe, phthalate-free silicone, it sits at the intersection of sexual wellness and self-care — a category that is increasingly recognised as part of overall health and wellbeing. If you've been curious about prostate stimulation but weren't sure where to start, the LELO Loki is one of the most well-regarded options available in the UK today. You can explore a wider range of sexual health products in our Condoms and Sexual Health collection.

Priced at £195.49, this isn't an impulse purchase — but for what it offers in terms of build quality, motor performance, and thoughtful ergonomic design, many users find it genuinely worthwhile. The Obsidian Black colourway gives it a sleek, understated look that feels considered rather than garish.

How Does the LELO Loki Work?

The LELO Loki uses two independent motors housed within a single ergonomic body. One motor sits at the insertable tip, angled to target the prostate gland internally. The second motor is positioned at the perineum arm — the external section that rests against the area between the scrotum and anus. Together, they create a dual-stimulation effect that many users describe as uniquely intense.

Eight distinct vibration modes allow you to customise intensity and pattern
The two motors can be controlled independently for tailored stimulation
The curved insertable arm is shaped to follow the natural anatomy of the rectum
Whisper-quiet motor technology keeps noise to a minimum
USB rechargeable with up to 2 hours of use per full charge

Who Should Consider Using the LELO Loki?

The LELO Loki is designed for adults with a prostate who want to explore internal and external stimulation. It suits both beginners who are new to prostate play and those with more experience looking for a reliable, well-built device. That said, it's worth thinking about whether it's right for your specific situation before purchasing.

Adults new to prostate stimulation who want a body-safe, ergonomic option
Those who prefer dual stimulation (internal and perineal simultaneously)
People who value rechargeable, waterproof devices for ease of use and hygiene
Individuals who want multiple vibration settings to explore different sensations

If you have any active rectal conditions, recent prostate surgery, or haemorrhoids, please speak to your GP before using any insertable device. Sexual health is a legitimate part of overall wellbeing, and there's no reason to feel awkward raising it with a healthcare professional.

How Does the LELO Loki Compare to Similar Devices?

Feature	LELO Loki (Obsidian Black)	Standard Prostate Massager
Motors	Dual independent motors	Typically single motor
Vibration modes	8 modes	Usually 3–5 modes
Material	Body-safe silicone (phthalate-free)	Varies — not always body-safe
Waterproof	Yes — fully waterproof	Often splash-proof only
Charging	USB rechargeable	Often battery-powered

Is the LELO Loki Suitable for Sensitive Skin?

Because the LELO Loki prostate massager is made from non-porous, phthalate-free silicone, it is generally well-tolerated even by those with sensitive skin. Non-porous materials don't harbour bacteria in the same way that porous alternatives can, which makes hygiene considerably easier to maintain. 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 or degrade the material. If you experience any skin irritation, discontinue use and consult a pharmacist or GP. You might also find our Skin Care collection helpful if you're managing sensitivity in intimate areas.

This product is a personal wellness device, not a medicine. However, speak to your doctor or pharmacist before using if you have an underlying medical condition, recent surgery, or are taking other medicines that may affect your prostate or rectal health.

Specifications of LELO Loki Obsidian Black

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

The LELO Loki Obsidian Black is a rechargeable, dual-motor prostate and perineum massager intended for adult sexual wellness use. It is not a medical device or a treatment for any clinical condition. Its purpose is to provide pleasurable stimulation of the prostate gland — sometimes called the "P-spot" — and the perineum simultaneously. The prostate is a walnut-sized gland located just below the bladder in people assigned male at birth, and it can be accessed via the rectum. Many people find prostate stimulation to be a deeply pleasurable experience, and devices like the LELO Loki are designed to make that exploration comfortable, safe, and enjoyable.

Sexual wellbeing is a recognised component of overall health. The NHS acknowledges that a satisfying sex life contributes positively to mental and physical health for many adults. The LELO Loki is one tool that some people use as part of that broader picture of self-care.

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

Before using any insertable device, it's sensible to consider whether it's appropriate for your current health situation. The following points are worth reviewing carefully.

Do not use the LELO Loki if you:

Have active haemorrhoids, anal fissures, or rectal inflammation
Have had recent prostate surgery or any rectal surgical procedure
Have been diagnosed with prostatitis in an acute phase — speak to your GP first
Are allergic or sensitive to silicone (rare, but worth checking)
Experience unexplained rectal pain or bleeding — seek medical advice before use

Drug and product interactions to be aware of:

No known drug interactions — this is a non-pharmaceutical device
Do not use silicone-based lubricants — they degrade silicone toy surfaces
Avoid oil-based lubricants if using with condoms, as oils can weaken latex
If you use topical rectal creams or suppositories, allow adequate time before use and clean the area thoroughly

How Should You Use the LELO Loki?

Using the LELO Loki correctly makes a significant difference to both comfort and enjoyment. Take your time, especially if this is your first experience with prostate stimulation. Rushing is the most common mistake — and it's entirely avoidable.

Charge the device fully before first use using the provided USB cable
Wash the device thoroughly with warm water and mild soap, then dry completely
Apply a generous amount of water-based lubricant to both the device and the body
Find a comfortable position — lying on your side with knees drawn up works well for many people
Insert the curved arm gently, allowing your body to guide the angle naturally
Ensure the perineum arm rests comfortably against the external area
Press the power button to activate, then use the control buttons to cycle through the 8 vibration modes
Adjust intensity gradually — start low and increase as comfortable

Indication	User Group	Recommended Starting Mode	Session Duration
Prostate stimulation (beginner)	Adults new to prostate play	Mode 1 (lowest intensity)	10–15 minutes
Dual stimulation (experienced)	Adults familiar with prostate devices	Mode 3–5 as preferred	Up to 2 hours (device limit)

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

The LELO Loki is not a medicine, so it does not carry pharmaceutical side effects. However, as with any insertable device, there are some physical considerations to be aware of. Most discomfort is avoidable with proper preparation and lubrication. If you experience persistent pain, stop use immediately. You can also browse our Pain Relief collection if you need support managing any mild discomfort.

Common experiences (usually avoidable with correct use):

Mild localised pressure or fullness during insertion
Temporary sensitivity in the perineal area after use
Minor skin irritation if insufficient lubricant was used

Less common concerns:

Discomfort or soreness if the device is used without adequate lubrication
Skin reaction if a non-compatible lubricant was used
Muscle tension or cramping if the pelvic floor is held tense during use

If you notice any rectal bleeding, significant pain, or signs of infection following use, seek medical advice promptly. These are not expected outcomes of correct use.

How Should You Store the LELO Loki?

Proper storage keeps the device hygienic and extends its lifespan. LELO includes a satin storage pouch with the Loki — use it. Storing the device loose in a drawer alongside other items risks surface scratches and contamination.

Store in the provided satin pouch in a cool, dry location
Keep away from direct sunlight and extreme heat, which can degrade silicone
Do not store in contact with other silicone toys — silicone-on-silicone contact can cause surface degradation over time
Ensure the device is fully clean and dry before storing
Charge to approximately 50% before long-term storage to preserve battery health
Keep out of reach of children

For general intimate health support, our Personal Lubricants collection includes water-based options that are fully compatible with silicone devices like the LELO Loki.

Frequently Asked Questions

Where can I buy the LELO Loki Obsidian Black online in the UK?

You can buy the LELO Loki Obsidian Black directly from Cured Pharmacy, a GPhC-registered UK online pharmacy. It is dispatched discreetly with no product branding visible on the outer packaging. Orders are processed securely and delivered to your door.

How does the LELO Loki prostate massager work?

The LELO Loki uses two independent motors — one positioned at the insertable tip to target the prostate internally, and one at the perineum arm for external stimulation. Both motors can be controlled separately, giving you full control over the type and intensity of sensation. Eight vibration modes let you explore a wide range of experiences.

How do I use the LELO Loki step by step?

Charge the device fully, then wash it with warm water and mild soap before use. Apply a generous amount of water-based lubricant to both the device and your body, then insert the curved arm gently while ensuring the perineum arm rests against the external area. Use the control buttons to power on and cycle through vibration modes, starting at the lowest setting.

What lubricant should I use with the LELO Loki?

Always use a water-based lubricant with the LELO Loki — silicone-based lubricants can degrade the silicone surface of the device over time, which may cause irritation or shorten the product's lifespan. Oil-based lubricants are also not recommended. You can find compatible options in our Personal Lubricants collection.

Is the LELO Loki safe to use?

Yes — the LELO Loki is made from body-safe, non-porous, phthalate-free silicone, which is widely considered one of the safest materials for intimate devices. It does not harbour bacteria in the way porous materials can, making it easier to keep hygienic. As with any insertable device, use adequate lubrication and stop immediately if you experience pain.

Who is the LELO Loki suitable for?

The LELO Loki is designed for adults with a prostate who wish to explore prostate and perineal stimulation, whether they are beginners or more experienced. It is not suitable for individuals with active rectal conditions, acute prostatitis, recent prostate or rectal surgery, or unexplained rectal bleeding — please consult your GP in those cases. It is suitable for solo or partnered use.

How do I clean the LELO Loki after use?

Wash the LELO Loki with warm water and a mild, unscented soap or a dedicated toy cleaner after every single use — this is non-negotiable for hygiene. Because it is fully waterproof, you can rinse it thoroughly without concern. Allow it to dry completely before storing it in the provided satin pouch.

How long does the LELO Loki battery last?

The LELO Loki offers up to 2 hours of use on a full charge, and a full charge takes approximately 2 hours via the included USB cable. It is worth charging the device fully before first use and before any extended session. For long-term storage, charge to around 50% to preserve battery health.

What are the alternatives to the LELO Loki?

Alternatives include other prostate massagers with single-motor designs, which tend to be less expensive but offer fewer stimulation options. The LELO Loki stands out for its dual-motor setup, 8 vibration modes, and fully waterproof body-safe silicone construction. If you're exploring sexual health products more broadly, our Condoms and Sexual Health collection has a range of options.

Can I use the LELO Loki if I have prostatitis?

If you have been diagnosed with acute prostatitis — an active infection or inflammation of the prostate — you should not use any insertable device until you have recovered and received clearance from your GP. Chronic prostatitis is a different matter, and your doctor is best placed to advise whether prostate stimulation is appropriate for your specific situation. Never self-treat prostate conditions with a consumer device.

Is the LELO Loki waterproof?

Yes, the LELO Loki is fully waterproof, meaning it can be used in the bath or shower and rinsed under running water for cleaning. This is a practical advantage over devices that are only splash-proof. Ensure the charging port is fully dry before connecting the USB cable after any water exposure.

How long can you use the LELO Loki for in a single session?

The device itself supports up to 2 hours of continuous use per charge. From a comfort perspective, especially for beginners, shorter sessions of 10–20 minutes are advisable initially to allow your body to adjust. There is no clinical maximum session length for a healthy adult, but listening to your body is always the right approach.

Does the LELO Loki make noise during use?

LELO designs its motors to operate quietly, and the Loki is no exception — it uses whisper-quiet motor technology that keeps sound to a minimum during use. At higher vibration intensities, some noise is inevitable, but it remains discreet compared to many comparable devices. This makes it a practical choice for those who value privacy.

What are the latest findings on prostate stimulation and health?

Research into prostate health continues to evolve. Some studies have explored the relationship between ejaculation frequency and prostate health, with certain findings suggesting a potential association between regular ejaculation and reduced prostate cancer risk — though this remains an area of ongoing research and should not be interpreted as a clinical recommendation. The NHS provides up-to-date information on prostate health at nhs.uk/conditions/prostate-problems. Always speak to your GP about any prostate health concerns.

How should I store the LELO Loki when not in use?

Store the LELO Loki in the provided satin pouch in a cool, dry place away from direct sunlight and heat sources. Avoid storing it in contact with other silicone toys, as silicone-on-silicone contact can cause surface degradation over time. Make sure the device is fully clean and dry before putting it away.

How Should You Use the LELO Loki?

Using the LELO Loki correctly is the single most important factor in having a comfortable and enjoyable experience. Take your time with each step — there is genuinely no need to rush, and a relaxed approach makes a significant difference, particularly if this is your first time using a prostate massager.

What Is the Correct Dose of the LELO Loki?

The LELO Loki is not a medicine, so there is no clinical "dose" in the pharmaceutical sense. However, thinking about session duration and intensity as you would a new exercise routine is a sensible approach — start gently and build gradually over time.

When Is the Best Time to Use the LELO Loki?

There is no medically prescribed time of day for using the LELO Loki — it is entirely a matter of personal preference and circumstance. Many people find that using it when they are relaxed, unhurried, and have privacy makes the experience considerably more comfortable and enjoyable. Ensuring you have visited the bathroom beforehand is also a practical consideration that many users find helpful.

If you are new to prostate stimulation, choosing a time when you are not tired or stressed gives your body the best chance to relax, which makes insertion more comfortable and the overall experience more positive.

How Long Can You Use the LELO Loki For?

The LELO Loki's battery supports up to 2 hours of continuous use per charge, which effectively sets a practical upper limit per session. From a physical comfort perspective, beginners are advised to keep initial sessions short — around 10 to 20 minutes — and gradually extend duration as they become more familiar with the sensations and their body's response. There is no clinical guidance on maximum long-term use frequency for healthy adults, but listening to your body and allowing adequate recovery time between sessions is always sensible.

Do not exceed the recommended device usage time per charge. If in doubt, speak to your pharmacist.

What Are the Most Common Experiences When Using the LELO Loki?

Because the LELO Loki is a personal wellness device rather than a medicine, it does not carry pharmaceutical side effects. That said, as with any insertable product, there are some physical experiences that users — particularly beginners — may notice. The good news is that most of these are entirely avoidable with correct preparation and technique.

A sensation of fullness or mild pressure during insertion, especially for first-time users
Temporary sensitivity or tenderness in the perineal area after use
Minor skin irritation if insufficient water-based lubricant was applied
Mild muscle tension in the pelvic floor if the body is not fully relaxed during use

What Are the Less Common Physical Concerns With the LELO Loki?

Less commonly, some users may experience discomfort that goes beyond the expected sensations of first-time use. These experiences are typically linked to incorrect technique, insufficient lubrication, or using the device when the body is not ready.

Soreness or aching in the rectal area following use without adequate lubrication
Skin reaction or localised irritation if a silicone-based or oil-based lubricant was used instead of a water-based one
Cramping or discomfort if the pelvic floor muscles were held tense throughout the session
Temporary urge to urinate, which can occur due to proximity of the prostate to the bladder

What Are the Serious Signs You Should Not Ignore?

Serious adverse events from correct use of a body-safe silicone device are rare. However, there are certain symptoms that should prompt you to stop use immediately and seek medical advice. These are not expected outcomes of normal, careful use.

Rectal bleeding — even minor spotting warrants medical assessment
Significant or worsening pain during or after use
Signs of infection such as fever, swelling, or unusual discharge
Difficulty passing urine following use

What Should You Do If You Experience Discomfort?

If you experience mild discomfort during use, stop the session, remove the device gently, and allow your body to rest. In most cases, discomfort resolves quickly once the device is removed. Applying a cool, damp cloth to the perineal area can help ease temporary sensitivity. If discomfort persists beyond a few hours, or if you notice any of the serious symptoms listed above, contact your GP or call NHS 111 for guidance.

For future sessions, ensure you are using a generous amount of water-based lubricant, that you are fully relaxed before insertion, and that you start at the lowest vibration intensity.

Can the LELO Loki Interact With Other Products or Medicines?

The LELO Loki has no known interactions with medicines. However, if you are using topical rectal preparations — such as haemorrhoid creams, suppositories, or any prescribed rectal treatments — you should allow sufficient time after application before using the device, and ensure the area is clean. Using the device alongside rectal medications without medical advice is not recommended. Always inform your GP or pharmacist if you have any active rectal or prostate conditions.

If you are concerned about any side effects, contact your pharmacist or GP immediately.
