Overview – Manufacturers and sellers of sex toys on sites like Amazon, AliExpress, and even many “reputable” sex store websites frequently claim their products are made of “liquid silicone.” This is a HUGE red flag. There is a strong chance the manufacturer or seller is misrepresenting the material or manufacturing process, and in some cases the toy may not actually be silicone at all.

Background – Many sex toy buyers have learned that silicone is the only generally body-safe soft toy material. As a result, they are constantly looking for the term “silicone” when shopping for a toy. This is a good thing, but it can give buyers a false sense of safety. A common example is someone being recommended a high-quality silicone toy, then finding a much cheaper knockoff on Amazon or AliExpress advertised as being made of “liquid silicone.” Because the listing prominently uses the word “silicone,” many buyers understandably assume they are purchasing a genuine body-safe silicone toy when the listing may never actually state that the toy is made of silicone or provide any meaningful material specifications. I go into more detail about some common misperceptions regarding silicone sex toy safety in this previous post.

Forms of Silicone – There are two main forms of silicone used in sex toys: LSR (Liquid Silicone Rubber) and HTV (High-Temperature Vulcanizing Silicone) – either can be body-safe or not. A few small indie toy makers also use RTV-2 (Room Temperature Vulcanizing Silicone – Two Part).

Curing Systems for Silicone – There are two types of curing used in sex toys: Platinum-cured silicone and peroxide-cured silicone. A third type of curing, tin-cured silicone, is possible but it is unsafe for internal use and is rarely used. Platinum-cured silicone can be LSR, HTV, or RTV-2, while peroxide-cured silicone is almost always HTV.

“Liquid Silicone” versus “Liquid Silicone Rubber” – Manufacturers and sellers frequently use the marketing term "liquid silicone." Within the context of silicone sex toy manufacturing, that term naturally implies Liquid Silicone Rubber (LSR), since peroxide-cured silicone is almost always manufactured using HTV compounds rather than LSR. Because LSR is virtually always platinum-cured, many buyers reasonably infer that a toy advertised as "liquid silicone" is made from platinum-cured silicone. Many reputable manufacturers that actually use platinum-cured silicone state that fact directly in their product descriptions because it is generally viewed as a premium material. When a listing relies only on the vague phrase "liquid silicone" instead of clearly identifying the material and curing system, buyers should treat that as a warning sign rather than evidence that the toy is genuine silicone. The term itself is neither a legal nor technical term and provides no reliable information about the toy's actual material or manufacturing process.

So What is “Liquid Silicone” – In reality, “liquid silicone” is a term with no legal or technical meaning whatsoever. Many of these toys might not actually be silicone at all. In some cases, they may instead be softened TPE or PVC, possibly with small amounts of silicone additives to mimic the feel - but this does NOT make them genuine silicone or body-safe. Since the term is meaningless, ask the seller whether their toy is actually silicone and, if so, what cure system and manufacturing process was used. If the seller cannot answer those questions clearly, consider that a warning sign. Also, unusually low prices may be another indication that the material is not really silicone or that the manufacturer/seller is misrepresenting the product.

Summary – "Liquid silicone" is a marketing term, not a recognized material specification. It does not tell you whether a toy is actually silicone, whether it is platinum- or peroxide-cured, whether proper manufacturing practices were followed, or whether the finished product is body-safe. When evaluating silicone toys, prioritize reputable manufacturers and transparent material specifications over marketing language.

Note: This is a revised version of a post I made yesterday. Several readers made constructive suggestions about readability and repetition, so I substantially reorganized and shortened it while preserving the underlying information. Thank you to everyone who offered thoughtful feedback.

Background – One of the most common pieces of advice given in discussions about anal play is "use more lube". In many situations, that is excellent advice. Proper lubrication is extremely important and significantly reduces friction between tissue and a toy. It can reduce irritation, chafing, abrasions, and many friction-related injuries. Unfortunately, this advice is often expanded far beyond what lubrication can actually accomplish. It is common to see people assume that if a toy is difficult to insert, difficult to use comfortably, painful, or simply too large, the solution is to add more lube. While lubrication is certainly an important part of safe anal play, it only addresses one specific factor: friction. It does not change anatomy, increase tissue strength, cause adaptation, or make unsafe practices safe.

Friction versus Stretching – Many discussions about anal safety unintentionally combine two completely different forces: friction and stretching. Friction occurs when tissue slides across the surface of a toy. Stretching occurs when the anal sphincters, anal canal, rectum, and supporting tissues are expanded beyond their resting size. Lubrication directly reduces friction, but it does not reduce the amount of stretching required by a given toy’s size. This distinction is extremely important because some injuries are caused primarily by friction while others are caused primarily by excessive stretching. A toy that requires significant stretching still requires that same amount of stretching whether it is lightly or heavily lubricated.

Lube Does Not Train the Sphincters or the Rectum – Adaptation occurs because tissue is gradually exposed to increasing levels of stress over time. The sphincters, rectum, surrounding connective tissue, and nervous system all require time to adapt to larger girths and/or longer durations of use. A toy can become easier to insert while still being too large for the user's current capabilities. A toy that exceeds what the body has safely adapted to can still cause overstretching, microtears, connective tissue strain, fissures, hemorrhoids, or other injuries regardless of how much lube is used. In some cases, excessive lube may actually make it easier to force a progression that the body is not yet prepared for – in either size and/or duration of use. Safe anal play is determined by what can be inserted, used, and removed without causing damage, not simply by what can be inserted.

Lube Does Not Always Decrease Pain or Discomfort – Discomfort or pain can sometimes be caused by inadequate lubrication and excessive friction. In those situations, adding more lube may completely solve the problem. However, discomfort or pain can also result from poor toy design, excessive force, or attempting to use a toy that exceeds the body's current capabilities. If pain is being caused by the resulting stretching or tissue stress, adding more lube does not address the underlying problem. It may simply make it easier to continue an activity that the body is signaling should stop.

Why People Overestimate the Importance of Lube – The myth persists because friction-related irritation is extremely common, especially among beginners. When adding more lube immediately solves that problem, it is easy to assume lubrication can solve every problem. In reality, lube is highly effective at reducing friction, but many of the factors that determine safety - such as toy size, progression, and toy design - have little or nothing to do with friction.

Summary – Lubrication is certainly an important part of safe anal play. It significantly reduces friction and helps prevent many friction-related injuries. However, lube does not increase the current capabilities of the sphincters or rectum, replace gradual tissue adaptation, compensate for poor toy design, eliminate stretching injuries, or make pain acceptable. A useful principle to remember is this: Lube reduces friction - not stretching. Understanding that distinction helps explain both why lubrication is so important and why it has limitations. Safe anal play still requires appropriate toy selection, gradual progression, appropriate durations of use, and paying attention to what your body is telling you.

What Lubrication Does Not Solve

• Does Not Increase Sphincter Capabilities – The internal and external anal sphincters do not become more capable of stretching further simply because additional lube is present. The amount that a sphincter must expand is determined by the diameter and shape of the toy, not by how slippery the toy is. A toy still requires the same amount of opening whether it is inserted with a small or large amount of lube.
• Does Not Train the Sphincters – Adaptation occurs because tissue is gradually exposed to increasing levels of stress over time. The sphincters, surrounding connective tissue, and nervous system all require time to adapt to larger diameters and/or longer durations of use. Lube can make this process more comfortable and reduce friction-related irritation, but it is not the mechanism that produces adaptation. Adaptation occurs through safe and gradual exposure to stretching.
• Does Not Train the Rectum – The rectum can also adapt over time to increases in toy girth and/or overall toy volume, but this adaptation occurs within the rectal wall and supporting tissues themselves. Again, lube may make insertion easier and more comfortable, but it does not accelerate the adaptation process or replace it. The rectum still requires time to adapt to increased pressure, volume, and stretching.
• Does Not Prevent All Types of Injuries – Many people assume that if sufficient lube is used, injuries cannot occur. This is incorrect. Lube reduces friction-related injuries, but it does not prevent injuries caused by excessive diameter, excessive force, rapid progression, prolonged pressure, poor toy design, unsafe depth, overstretching of tissues, or connective tissue strain. A heavily lubricated toy can still place more stress on tissue than it can safely tolerate. While lube may help protect the surface of the tissue, it cannot prevent damage occurring deeper within the supporting structures. Lube is extremely important, but it should be viewed as one component of safety rather than a complete safety system by itself.
• Does Not Make a Poorly Designed Toy Safe – Toy design and lubrication are separate issues. A poorly designed toy remains poorly designed regardless of how much lube is used. Sharp transitions, excessively bulbous shapes, too much texture, abrupt diameter changes, inadequate necks, unsafe insertable lengths, and other anatomical design problems are not corrected by additional lube. Lube may reduce surface friction, but it cannot change how a toy interacts with the anatomy of the anal canal, rectum, or rectosigmoid junction.
• Does Not Make a Larger Toy Automatically Safe – A toy can become easier to insert while still being too large for the user's current capabilities. Reduced friction lowers resistance during insertion, but it does not reduce the amount of expansion required from the sphincters, anal canal, rectum, or supporting tissues. A toy that exceeds what the body has safely adapted to can still cause overstretching, microtears, connective tissue strain, or other injuries regardless of how much lube is used. In some cases, excessive lube may actually make it easier to force a progression that the body is not yet prepared for.
• Does Not Replace Safe Anal Training and Progression – One of the most dangerous misconceptions in anal play is the belief that successful insertion automatically means a toy is safe. Insertion only demonstrates that a toy can be inserted. It does not demonstrate that the sphincters, connective tissue, rectum, or supporting structures have adapted safely to that size. It does not indicate that anal play will be safe, that removal will be easy, or that tissue injury is not occurring. Likewise, lube does not replace gradual progression, appropriate sizing, recovery periods, or the adaptation that occurs through repeated exposure over time. These factors remain important whether someone is using plugs, dildos, prostate toys, or other anal toys. Safe anal play is determined by what can be inserted, used, and removed without causing damage, not simply by what can be inserted.
• Does Not Always Decrease Pain or Discomfort – Pain can sometimes be caused by inadequate lubrication and excessive friction. In those situations, adding more lube may completely solve the problem. However, pain can also result from excessive stretching, poor toy design, hemorrhoids, fissures, tissue injury, excessive force, or attempting to use a toy that exceeds current capabilities. If pain is being caused by stretching or tissue stress, adding more lube does not address the underlying problem. It may simply make it easier to continue an activity that the body is signaling should stop. For plugging in particular, discomfort is often caused by factors such as excessive girth, excessive wear duration, poor neck design, pressure hotspots, or pressure from the base, none of which are necessarily solved by additional lube.

Why People Overestimate the Importance of Lube – The myth that lube solves many issues persists because lubrication often does solve the immediate problem someone is experiencing. Friction-related irritation is extremely common, especially among beginners, so adding more lube frequently provides immediate relief. People then incorrectly assume that because additional lubrication solved one problem, it can solve all problems. In reality, lube is highly effective at reducing friction, but reducing friction does not address many of the other mechanical and anatomical factors that determine whether anal play is safe. This is especially true as toy size, duration of use, or intensity of play increase, where gradual progression and good toy design become equally important components of safety.

Summary – Lubrication is certainly an important part of safe anal play. It significantly reduces friction and helps prevent many friction-related injuries. However, lube does not increase the current capabilities of the sphincters, train the rectum, replace gradual tissue adaptation, compensate for poor toy design, eliminate stretching injuries, or make pain acceptable. A useful principle to remember is this: Lube reduces friction - it does not reduce stretching. Understanding that distinction helps explain both why lubrication is so important and why it has limitations. Safe anal play still requires appropriate toy selection, gradual progression, appropriate durations of use, and paying attention to what your body is telling you.

Background – One of the most common pieces of advice given in discussions about long-term plugging is "use more lube." In many situations, that is excellent advice. Proper lubrication is extremely important and significantly reduces friction between tissue and a plug. It can reduce irritation, chafing, abrasions, and many friction-related injuries. Unfortunately, this advice is often expanded far beyond what lubrication can actually accomplish. It is common to see people assume that if a plug is difficult to insert, difficult to wear comfortably, painful, or simply too large, the solution is to add more lube.

A plug can become easier to insert while still being too large for the user's current capabilities.

Just a heads-up for anyone in the US who has been considering purchasing a new plug.

Mr. S Leather is currently running one of their relatively uncommon free shipping promotions with no minimum order requirement. Normally, free shipping only applies to orders over $99, which can make purchasing a single plug significantly more expensive once shipping is added.

Since Mr. S carries several plugs that are frequently discussed in this community (including Square Peg Toys' Eggs and Topped Toys' Gape Keepers), this may be a good opportunity for members who have been considering one of those plugs but have been holding off because of shipping costs.

Note: Mr. S Leather's website (mr-s-leather.com) is very NSFW and contains explicit sexual content and imagery.

I have no affiliation with Mr. S Leather and am not receiving anything for mentioning it. I simply noticed the promotion and thought some members might find it useful.
