What is lube?
Lube, short for lubricant, is a specifically formulated gel or liquid that can be applied to intimate areas, designed to increase pleasure and reduce friction during intimate activities.
What is lube used for?
Lube is used to make sex more comfortable and enjoyable by reducing friction. It can also be used during solo play (masturbation for both men and women), with sex toys, anal sex, foreplay, or to make condom use smoother.
What is the best lubricant for vaginal dryness?
Lubricants that support the body rather than overriding it are often preferred for vaginal dryness. Vaginal tissue is delicate and highly sensitive to formulation, which is why many people look for lubricants that are pH-balanced, microbiome-friendly, and clinically assessed. For those experiencing dryness, including during hormonal shifts, periods of stress, or life stage changes, silicone-based lubricants are commonly chosen for their longer-lasting glide. Because they sit on the skin rather than absorbing immediately, they can provide sustained comfort without frequent reapplication. What’s included in a lubricant matters just as much as what’s left out. Lubricants that avoid glycerin, parabens, artificial fragrance, harsh preservatives, and unnecessary additives are often favoured, as these ingredients have been associated with irritation or microbiome disruption in sensitive users.
Why should I use lube?
There are multiple reasons why individuals can benefit from using a lubricant.
It can –
Enhance foreplay by increasing arousal and intensifying sensation during the lead-up to sex.
Support a smooth and natural transition from touch to penetration, helping maintain connection and flow.
Pair beautifully with sex toys to elevate solo or partnered play, just be sure your lube is toy-safe by checking compatibility guidelines.
Reduce discomfort for those experiencing vaginal dryness, which helps reduce friction and improves overall ease.
Heighten overall sensation, supporting natural moisture making every movement feel more fluid, responsive, and pleasurable.
Help protect delicate skin by reducing the risk of microtears or irritation caused by friction.
Support longer-lasting pleasure, especially during extended sessions or slower, more sensual experiences.
Foster confidence and presence, allowing you to stay in the moment without discomfort or distraction.
How much lubricant should I use?
Use as much as you need to. If this is your first time trying it, start with two pumps/ a pea-sized drop and gently apply it with your fingers, then add more if you’d like.
Is it safe to use saliva as a lubricant?
While saliva may seem convenient, it’s not generally recommended as a lubricant. Saliva can dry out quickly, disrupt vaginal pH, and most importantly, it can introduce bacteria to your intimate areas that may lead to infections.
What are the different types of lubricants and what type of lube should I use?
The type of lubricant you choose depends on your body, your preferences, and how you plan to use it. The three main types are silicone-based, water-based, and oil-based.
Silicone-based lubricants, such as Opal, are renowned for their luxurious texture, long-lasting glide, and hypoallergenic properties. Opal is made with two high-grade silicones, dimethicone and dimethiconol. Opal is also compatible with silicone sex toys but not all silicone lubricants are, so please check! One thing to note: they can make surfaces slippery, so a little caution goes a long way, especially if you’re using them in the shower.
Water-based lubricants utilise water as their primary ingredient and combine other ingredients to alter the texture and thickness of the lubricant. Water-based products usually contain preservatives and stabilisers to ensure there is no bacterial growth, this is common for any cosmetic product containing water. Some preservatives and thickeners have been known to cause irritation.
Oil-based lubricants use either natural or synthetic oils and tend to be very moisturising. However, they’re not compatible with latex condoms and can alter vaginal or rectal pH, potentially leading to irritation or imbalances. For these reasons, they’re less commonly recommended unless specifically formulated for intimate use.
What about scented, flavoured, tingling or cooling lubricant?
Lubricants that are scented, flavored, or designed to create tingling or cooling sensations can seem fun and enticing but they’re not always suitable for everyone, especially for those with sensitive skin or a delicate intimate microbiome.
These types of lubricants often contain ingredients such as menthol, peppermint oil, cinnamon, glycerin, artificial sweeteners (like aspartame or saccharin), and synthetic fragrances to create their effects. While these can offer novelty, they can also increase the risk of irritation, allergic reactions, or disruption to your natural vaginal flora particularly in sensitive areas.
Many of these ingredients are known to be common irritants in personal care products, and their impact is amplified when applied to intimate skin. Menthol and peppermint oil, for example, create a cooling or tingling sensation by triggering nerve receptors but they can also cause burning, dryness, or inflammation for some users. Similarly, artificial sweeteners used in flavoured lubricants can alter the pH balance or feed harmful bacteria, increasing the likelihood of infections such as thrush or bacterial vaginosis (BV).
If you’re considering using a scented or speciality-effect lubricant, always read the full ingredient list carefully. We recommend patch testing first and avoiding these products altogether if you have a history of sensitivity or are prone to irritation.
When it comes to your intimate health, gentleness, safety, and high-quality formulation matter; look for lubricants that are dermatologically tested, gynaecologist-approved, and free from unnecessary irritants. Especially if you’re using them regularly.
Can condoms and lube be used together?
Yes, but make sure the lube is condom compatible. If it is, add the lubricant to the outside of the condom once it is on. Opal has been clinically tested to ensure it is safe to use with latex and polyisoprene condoms.
Watch out for oil-based lubricants. These are generally not safe to use with condoms, as the oil can cause the latex to break or fail.
How long can I use a bottle of lube after opening it?
Most lubricants last up to 12–24 months after opening, depending on their ingredients. Please check the packaging as this will vary per product. Opal will last 24 months after opening.
Can I use lube for masturbation?
Absolutely. Lubricant can enhance solo play by reducing friction and increasing comfort and pleasure. Silicone lubricants, such as Opal, are ideal for providing a long-lasting glide and a more luxurious experience.
Should I use lube for anal sex?
Yes, it is highly recommended. The anus doesn’t self-lubricate like the vagina, so using a long-lasting, silky lubricant like Opal can help increase comfort, reduce friction, and avoid injury. Silicone lubricant is usually recommended in this instance as it does not evaporate and therefore reduces the need for reapplication.
What is the preferred lubricant for menopause?
Lubricants that are often preferred for menopause are usually formulated to be microbiome-friendly, pH-balanced, and free from irritants. Opal has undergone independent clinical testing to ensure it’s suitable for sensitive skin and is microbiome friendly, and free from irritants.
What lubricant do doctors recommend?
Doctors don’t universally recommend any type of lubricant. We have cited the below which you can use as a general reference – ‘Oil-based lubricant is not recommended since it is incompatible with latex condoms and is more likely to irritate genital epithelium and negatively impact genital microbiota. When comparing silicone and water-based lubricant, silicone based lubricant lasts longer but is more difficult to wash off… Water-based lubricant is also more likely than silicone-based lubricant to contain potentially irritating ingredients and properties, such as glycerol, propylene glycol, parabens, or a high osmolality.’

What are the most popular lubes for sex?
Some of the most popular lubricants for sex include silicone-based lubes for their longevity and water-based lubes for versatility. Opal by Ples’Jour is a popular choice for many people looking for a product that performs well while also being safe.
Can I use coconut oil as a lubricant?
Coconut oil is often perceived as a natural alternative for intimate use, however it isn’t designed for use on vaginal tissue. While it does have antimicrobial properties, these are not selective and can interfere with the beneficial bacteria that help maintain a healthy vaginal environment. Coconut oil also hasn’t been clinically tested for regular vaginal use, which means its safety and long-term effects in this context aren’t well understood. For intimate care, products that are specifically formulated and clinically evaluated for delicate tissue are generally the safer, more reliable choice.
What is the best personal lubricant that doesn’t dry out?
Silicone-based lubricants are often preferred if you’re looking for a lube that doesn’t dry out. Unlike water-based options, they don’t evaporate, which means they tend to stay slippery for longer without needing frequent reapplication. This makes them a popular choice for extended intimacy.
Which sex lubricant lasts longest?
Silicone-based lubricants typically last the longest without needing reapplication. Opal’s ultra-smooth formula is designed for extended glide and minimal interruption while being non-sticky and moisturising.
Can I use lubricant if I’m pregnant?
Lubricants that are free from harmful chemicals and fragrances are generally safe to use during pregnancy. However, it’s always best to consult your healthcare provider.
What are the best natural or organic lubricants?
There are various natural and organic lubricants on the market with clean formulations including Good Clean Love and Playground. However, “natural” doesn’t always mean safe. Try to use a product is dermatologically tested and approved by a gynaecologist. Please also check the ingredients as some naturally occurring and organic ingredients can cause irritation to such sensitive areas of your body.
How important is pH balance in a vaginal lubricant?
pH balance is very important in a vaginal lubricant. The vagina has a naturally acidic environment that helps protect against irritation and infection, and products that don’t respect this balance can disrupt it. A lubricant with an unsuitable pH may cause discomfort, dryness, or irritation, especially with regular use. Choosing a well-formulated lubricant designed specifically for vaginal use and tested for compatibility with the vaginal environment, helps maintain comfort and supports intimate health.
What are the key differences between water-based and silicone lubricants?
Water-based and silicone lubricants differ in texture, longevity, and how they interact with the body. Water-based lubricants tend to feel lighter at first but absorb or evaporate quickly, which can lead to dryness and frequent reapplication. They’re easy to wash off, but may become sticky over time. Silicone lubricants are more stable and long-lasting, sitting on the skin rather than absorbing into it. This creates a consistently smooth, cushioned feel with minimal interruption. For those seeking lasting comfort, enhanced sensation, or support for dryness or sensitivity, silicone lubricants are often preferred.
Which lube lasts longer, water or silicone?
Silicone lubricants last significantly longer than water-based formulas. They don’t evaporate or absorb into the skin as quickly, making them ideal for longer intimacy and reduced friction.
What’s the most comfortable vaginal lubricant?
For many people, the most comfortable lubricants are those designed specifically for intimate skin, which are smooth, non-sticky, pH-considerate, and free from irritants. Many people with sensitivity find well-formulated silicone lubricants the most comfortable option; they often contain fewer ingredients.
Does tingling lube irritate sensitive skin?
Yes, tingling or warming lubricants often irritate sensitive skin because the ingredients used to create these sensations are commonly irritants. They typically work by stimulating nerve endings or increasing blood flow, which can trigger burning, stinging, or discomfort, particularly on delicate vaginal tissue. For anyone with sensitive skin, a history of irritation, or recurring imbalance, it’s generally best to avoid these formulas and choose a lubricant designed purely for comfort and skin compatibility.
What lube do you recommend during pregnancy?
During pregnancy, it’s advised to consult your healthcare provider. It is often preferred to use a gentle, non-irritating lubricant that’s free from harsh additives. Comfort, safety, and skin compatibility are important as well as using a product that will not alter or affect the vaginal microbiome or pH. Opal lubricant has been clinically tested to ensure it does not affect the vaginal microbiome and is suitable for sensitive skin and all skin types.
Does using lube reduce my chances of conceiving?
Using lubricant does not automatically reduce your chances of conceiving, but the type of lubricant matters. Some formulas can affect sperm movement due to their ingredients or pH, which may make it harder for sperm to reach the egg. Choosing a well-formulated, gentle lubricant allows you to prioritise comfort without compromising your chances of conception. Always consult your healthcare provider.
Best lube for menopausal vaginal dryness – what actually works?
For menopausal vaginal dryness, longevity and skin comfort are key. As hormone levels change, natural lubrication may decrease and the tissue can feel more delicate meaning short-lasting water-based lubes often absorb too quickly and may not provide sustained relief. Many people find that high-quality silicone lubricants work best because they provide lasting slip, reduce friction without irritating sensitive tissue, and don’t need frequent reapplication.
Which lubes are gentle enough for sensitive users?
Lubricants with minimal, well-tested ingredients and no added fragrances, tingling agents, or unnecessary additives are generally best for sensitive users. Formulation quality matters more than marketing claims.
Why do some lubes cause burning or irritation?
Burning or irritation is usually caused by the ingredients in a lubricant rather than the lubricant itself. Many formulas contain additives such as warming or tingling agents, fragrances, flavourings, glycerin or parabens that can be irritating to delicate intimate tissue. In some cases, an unsuitable pH or high osmolality can also disrupt the vaginal environment, leading to stinging or discomfort. Because vaginal skin is especially sensitive, even ingredients that are common in everyday cosmetics can cause irritation. Choosing a lubricant with a minimal, well-considered ingredient list and one designed specifically for intimate use can help reduce the risk of discomfort.
Is silicone lube actually worth it?
For many people, yes, silicone lubricant is worth it because of how it performs. Unlike water-based formulas that absorb or dry out quickly, silicone lubricants stay smooth and slippery for much longer without needing frequent reapplication. Silicone isn’t absorbed into the skin the same way water-based lubes are, so it maintains its feel longer and creates a consistently comfortable experience. If you value lasting slip and minimal interruption, a high-quality silicone lubricant can make a real difference.
Why is paraben-free lube recommended?
Paraben-free lubricants are often preferred because some research suggests that parabens may act as endocrine disruptors, meaning they could interfere with hormone activity in the body. Because intimate tissue is more absorbent than skin elsewhere, ingredients used in this area may be absorbed more readily, especially with regular use. For this reason, many clinicians and consumers choose paraben-free formulations as a more considered option for intimate care.
What’s the best travel-friendly lube?
A good travel choice will come in thoughtfully designed packaging that’s easy to pack and doesn’t add bulk. Opalette by Ples’Jour was designed with intention, including a glass travel-ready bottle in 12ml, that feels secure in a bag and delivers long-lasting comfort with minimal fuss.
What’s the difference between hybrid and silicone lube?
Hybrid lubricants combine water and silicone, offering some longevity but often less durability than pure silicone. Silicone lubricants often provide the longest-lasting slip and smoothest feel.
