What Is the COLT Big Boy Black Anal Play Toy?

If you've been exploring anal play and want to take things a step further, the COLT Big Boy – Black could be exactly what you're looking for. Made by COLT, a well-regarded name in adult wellness products, this toy is designed with both size and comfort in mind. It's built for those who want a fuller, more satisfying experience — and it's available right here at Cured Pharmacy for £34.99. You can also browse our wider range of personal lubricants to find the right pairing for this product.

The COLT Big Boy – Black is a anal play toy that prioritises body-safe design. Its smooth, firm construction allows for controlled insertion, and the flared base is an essential safety feature — it prevents the toy from travelling beyond the rectum, which is a critical consideration for any anal product. This isn't a toy to rush with. Take your time, use plenty of lubricant, and listen to your body throughout.

How Does the COLT Big Boy Black Work?

Anal toys work by providing physical stimulation to the highly sensitive nerve endings in and around the anal canal and rectum. The COLT Big Boy – Black is shaped to apply gentle but firm pressure to these areas, which many people find pleasurable. Here's what makes it function effectively:

The tapered tip allows for gradual, comfortable insertion at your own pace.
The widened body provides a sense of fullness that stimulates the internal anal sphincter and surrounding tissue.
The flared base sits securely outside the body, acting as a safety stop to prevent full insertion.
The smooth surface reduces friction, especially when used alongside a compatible lubricant.

It's worth noting that the anal canal does not self-lubricate the way the vagina does. This means using a generous amount of personal lubricant is not optional — it's essential for both comfort and safety.

Who Should Use the COLT Big Boy Black?

This product is best suited to adults who already have some experience with anal play and are looking to progress to a larger size. It is not typically recommended as a first toy for complete beginners, given its dimensions. That said, with patience and the right preparation, it can be used safely by a wider range of people.

Adults with prior experience using smaller anal toys who want to size up.
Individuals who enjoy a sense of fullness during anal stimulation.
Those who want a body-safe, non-vibrating option for solo or partnered play.
People who prefer a firm, smooth texture over softer or more flexible materials.

It is not suitable for anyone with active haemorrhoids, anal fissures, inflammatory bowel conditions affecting the rectum, or those who have had recent rectal or anal surgery. If you have any of these conditions, please speak to your GP before using any anal toy.

Is the COLT Big Boy Black Safe to Use and How Should It Be Stored?

Safety is everything when it comes to anal play toys. The COLT Big Boy – Black should always be used with a water-based lubricant to protect both the toy's material and your body. Silicone-based lubricants can degrade certain toy materials, so check compatibility before use. If you experience any sharp pain, bleeding, or significant discomfort, stop immediately and seek medical advice. You can also explore our haemorrhoids and piles section if you're managing any related rectal conditions.

Store the toy in a clean, dry pouch away from direct sunlight and heat. Clean it thoroughly with warm water and a mild, fragrance-free soap — or a dedicated toy cleaner — before and after every single use. Never share toys without using a new condom over them each time, as this reduces the risk of transmitting sexually transmitted infections.

This product is a personal wellness device. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

Specifications of COLT Big Boy - Black

What Is the COLT Big Boy Black and What Is It Used For?

The COLT Big Boy – Black is a non-medicated personal wellness device designed for anal stimulation. It is used by adults who wish to explore or enhance anal play, either alone or with a partner. Unlike medicated products, it contains no active pharmaceutical ingredients. Its purpose is purely physical — to provide pleasurable stimulation through safe, controlled anal insertion.

Anal play is a normal part of human sexuality for many people. The anal region contains a dense network of nerve endings, and for some individuals — including those with a prostate — stimulation of this area can be particularly pleasurable. The COLT Big Boy – Black is designed to facilitate this safely, provided it is used correctly and with appropriate preparation.

What Do You Need to Know Before Using the COLT Big Boy Black?

Before using this product, it's important to be aware of the following contraindications and warnings:

Do not use if you have active haemorrhoids, anal fissures, or rectal prolapse.
Do not use following recent anal or rectal surgery without medical clearance.
Do not use if you have inflammatory bowel disease affecting the rectum (e.g. Crohn's disease or ulcerative colitis) without speaking to your gastroenterologist first.
Do not use if you experience pain during insertion — stop immediately and seek advice.
Not suitable for children or young people under 18.
Do not use internally without a flared base or retrieval cord — the COLT Big Boy Black has a flared base, which is a key safety feature.

There are no known drug interactions associated with this non-medicated device. However, if you are using any topical rectal medications — such as those for haemorrhoids — avoid using this toy at the same time, as it may interfere with the medication's absorption or cause irritation.

No known pharmacological drug interactions.
Avoid concurrent use with topical rectal treatments.

How Should You Use the COLT Big Boy Black?

Using an anal toy safely requires preparation, patience, and the right products. Never rush the process. Here is a step-by-step guide:

Wash your hands thoroughly with soap and water before handling the toy.
Clean the COLT Big Boy – Black with warm water and a mild, fragrance-free soap or dedicated toy cleaner. Rinse well and allow to dry.
Apply a generous amount of water-based personal lubricant to both the toy and the anal opening.
Find a comfortable position — lying on your side or back with knees bent is often easiest.
Gently press the tapered tip against the anal opening and apply slow, steady pressure. Do not force insertion.
Pause and breathe if you feel resistance. Allow the muscles to relax naturally.
Insert to a comfortable depth, ensuring the flared base remains outside the body at all times.
When finished, remove slowly and gently. Clean the toy immediately after use.

There is no fixed "dose" for a personal wellness device. Use it for as long as is comfortable, and never leave an anal toy inserted for extended periods without checking in with how your body feels. You can find compatible products in our personal lubricants collection.

Frequently Asked Questions

Where can I buy the COLT Big Boy Black online in the UK?

You can buy the COLT Big Boy – Black directly from Cured Pharmacy online for £34.99. It is dispatched with discreet packaging so nothing on the outside indicates the contents. Ordering is straightforward and delivery is available across the UK.

Is the COLT Big Boy Black body-safe?

The COLT Big Boy – Black is designed to be body-safe for anal use. Always inspect the toy before each use for any signs of damage, cracking, or discolouration, and discard it if you notice any changes. Cleaning it properly before and after every use is essential to maintaining hygiene and safety.

What lubricant should I use with the COLT Big Boy Black?

A water-based personal lubricant is the safest choice for use with the COLT Big Boy – Black. Silicone-based lubricants can degrade certain toy materials over time, so it is best to avoid them unless you have confirmed compatibility. You can browse a range of suitable options in our personal lubricants collection.

How do I clean the COLT Big Boy Black properly?

Clean the COLT Big Boy – Black with warm water and a mild, fragrance-free soap or a dedicated toy cleaner before and after every single use. Rinse thoroughly to remove all soap residue, then allow it to air dry completely before storing. Never submerge it in boiling water unless the manufacturer's instructions confirm it is safe to do so.

Is the COLT Big Boy Black suitable for beginners?

The COLT Big Boy – Black is a larger-sized anal play toy and is generally better suited to those who already have some experience with anal stimulation. If you are new to anal play, it is advisable to start with a smaller toy and gradually work your way up in size. Rushing the process can cause discomfort or injury.

Can I use the COLT Big Boy Black if I have haemorrhoids?

You should not use any anal toy, including the COLT Big Boy – Black, if you have active haemorrhoids, anal fissures, or have recently had rectal surgery. Using a toy in these circumstances can worsen the condition and cause bleeding or significant pain. Speak to your GP before resuming use of any anal toy if you are managing a rectal condition — you can also find helpful information in our haemorrhoids and piles section.

How does the COLT Big Boy Black work for prostate stimulation?

The prostate gland sits just a few centimetres inside the rectum along the anterior (front) wall, and anal toys can stimulate it indirectly through the rectal wall. The COLT Big Boy – Black, with its firm construction and fuller body, can apply pressure to this area during use. Not everyone finds prostate stimulation pleasurable, so explore at your own pace and comfort level.

What are the alternatives to the COLT Big Boy Black?

If the COLT Big Boy – Black feels too large, smaller COLT anal toys or graduated anal plug sets are good alternatives that allow you to build up gradually. Vibrating anal toys are another option if you prefer added stimulation. Always choose a toy with a flared base or retrieval cord for safe anal use.

How long can I use the COLT Big Boy Black for in a single session?

There is no fixed time limit, but it is important to listen to your body throughout use. If you experience any discomfort, soreness, or numbness, remove the toy immediately. Extended use without breaks can cause temporary muscle fatigue of the anal sphincter, so take your time and do not push beyond what feels comfortable.

What should I do if I experience pain when using the COLT Big Boy Black?

Stop using the toy immediately if you experience sharp or significant pain. Pain during anal play is a signal that something is wrong — it may mean you need more lubrication, a smaller size, or more time to relax the muscles. If pain persists after removing the toy, or if you notice any bleeding, seek medical advice from your GP promptly.

Can I share the COLT Big Boy Black with a partner?

Sharing anal toys carries a risk of transmitting sexually transmitted infections (STIs), including those caused by bacteria and viruses. If you do share the toy, always place a new condom over it before each person uses it, and clean it thoroughly between uses. For more information on sexual health, visit our condoms and sexual health collection.

Does the COLT Big Boy Black require batteries or charging?

No — the COLT Big Boy – Black is a non-vibrating, non-electronic toy. It requires no batteries or charging, which makes it simple to use and maintain. This also means there are no mechanical components that could fail over time.

How should I store the COLT Big Boy Black?

Store the COLT Big Boy – Black in a clean, dry pouch or storage case away from direct sunlight and heat. Keep it separate from other toys to prevent material-to-material reactions that can degrade the surface. Always ensure it is fully dry before storing to prevent bacterial growth.

What is the COLT Big Boy Black made from?

The COLT Big Boy – Black is made from a firm, smooth material designed for body-safe anal use. Always check the product packaging for the specific material composition, as this will also determine which lubricants are compatible. If you have known sensitivities to certain materials, check before purchasing.

Are there any latest studies or research on anal toy safety?

Research on sexual wellness devices is an evolving field. Current guidance from sexual health organisations emphasises the importance of using toys with a flared base for anal use, maintaining thorough hygiene, and using appropriate lubrication to minimise the risk of injury or infection. Always follow manufacturer instructions and consult a healthcare professional if you have any concerns about safe use.

How Should You Use the COLT Big Boy Black?

Using the COLT Big Boy – Black safely starts with preparation. Before you begin, wash your hands thoroughly and clean the toy with warm water and a mild, fragrance-free soap. Apply a generous amount of water-based personal lubricant to both the toy and the anal opening — never attempt insertion without adequate lubrication, as the anal canal does not self-lubricate.

Follow these steps for safe, comfortable use:

What Is the Correct Dose of the COLT Big Boy Black?

As a non-medicated personal wellness device, there is no pharmacological dose associated with the COLT Big Boy – Black. Use is guided entirely by personal comfort and experience level. The table below provides a general guide based on user experience.

When Is the Best Time to Use the COLT Big Boy Black?

There is no medically defined "best time" to use the COLT Big Boy – Black. Most people find it easiest to use when they are relaxed and unhurried, as stress and tension can cause the anal sphincter to tighten, making insertion more difficult and potentially uncomfortable. Many users find that a warm bath beforehand helps the muscles relax naturally.

Avoid using the toy immediately after eating a large meal, and ensure you have enough time to prepare properly, use the toy comfortably, and clean it thoroughly afterwards without rushing.

How Long Can You Use the COLT Big Boy Black For?

There is no fixed maximum duration for a single session, but it is important to listen to your body throughout. If you experience any discomfort, soreness, or numbness, remove the toy immediately and allow time to recover before using it again. Extended or very frequent use without adequate recovery time may cause temporary muscle fatigue of the anal sphincter.

If you notice any persistent discomfort, bleeding, or changes in bowel habits following use, stop using the product and consult your GP. Regular inspection of the toy for signs of wear or damage is also important — replace it if you notice any cracks or changes in texture.

Do not exceed the recommended dose. If in doubt, speak to your pharmacist.

What Are the Most Common Side Effects of the COLT Big Boy Black?

Because the COLT Big Boy – Black is a non-medicated device, it does not cause pharmacological side effects. However, physical side effects can occur — particularly if the toy is used without sufficient lubrication, if insertion is rushed, or if the toy is too large for the user's current level of experience.

Anal soreness or discomfort during or after use.
Mild irritation of the anal mucosa (the lining of the anal canal).
Temporary tightness or fatigue of the anal sphincter muscles.
Mild bruising of the surrounding tissue if insertion was forced.

What Are the Less Common Side Effects of the COLT Big Boy Black?

Less common side effects are more likely to occur if the toy is used incorrectly, shared without protection, or if the user has an underlying rectal condition. These are not typical with correct use but are important to be aware of.

Minor bleeding from small mucosal tears — stop use immediately if this occurs.
Skin irritation or allergic reaction to the toy material.
Discomfort lasting more than 24 hours after use.
Temporary changes in bowel sensation following extended use.

What Are the Serious Side Effects of the COLT Big Boy Black?

Serious side effects are rare when the COLT Big Boy – Black is used correctly, but they can occur if safety guidelines are ignored. Rectal perforation is an extremely rare but serious risk associated with any anal toy used with excessive force. Signs of a serious problem include severe abdominal or rectal pain, significant rectal bleeding, fever, or an inability to pass stool. These symptoms require immediate medical attention — call 999 or go to your nearest A&E department.

Never attempt to retrieve a toy that has become fully inserted without a flared base — this is a medical emergency. The COLT Big Boy – Black has a flared base specifically to prevent this from occurring.

What Should You Do If You Experience Side Effects?

If you experience mild discomfort, remove the toy, rest, and allow the area to recover. Applying a small amount of a soothing, fragrance-free cream to the external anal area may help with minor irritation — you can explore suitable options in our creams and ointments collection. If symptoms persist beyond 24 hours, or if you notice bleeding, seek advice from your GP or a sexual health clinic.

For any allergic reaction — such as swelling, hives, or significant skin irritation — discontinue use immediately and contact a healthcare professional. If you experience a severe allergic reaction with difficulty breathing or swelling of the face, call 999 immediately.

Can the COLT Big Boy Black Interact With Other Products?

The COLT Big Boy – Black has no pharmacological drug interactions. However, using it alongside topical rectal medications — such as haemorrhoid creams or suppositories — is not advisable, as the toy may interfere with the medication's absorption or cause additional irritation to already-sensitive tissue. If you are using any rectal treatments, speak to your pharmacist before using this toy. You can find relevant products in our haemorrhoids and piles section.

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