If you're comparing lidocaine vs benzocaine delay spray, you've already done your homework. Both ingredients work by reducing sensitivity in the penis to help you last longer. The difference comes down to strength, speed, and what format they tend to come in. This guide covers both, side by side, so you can make the right choice the first time.

How Both Ingredients Work
Lidocaine and benzocaine are both local anaesthetics. They work by temporarily blocking the sodium channels in nerve cells, which stops those nerves from firing the sensation signals that build towards ejaculation. Apply either one to the penis, wait for it to absorb, and you get a controlled reduction in sensitivity for the next hour or so.
Neither ingredient enters your bloodstream in any meaningful amount when used topically and in the doses found in commercial delay sprays. The effect is localised, temporary, and reverses naturally as the drug metabolises.
The two chemicals belong to different anaesthetic families - lidocaine is an amide, benzocaine is an ester. This distinction matters mainly if you've had an allergic reaction to a local anaesthetic in the past, as the allergy usually doesn't cross between the two families.
Lidocaine: Faster, Stronger, More Widely Used
Lidocaine is the active ingredient in the majority of dedicated delay sprays. It's been in clinical use since the 1940s and is one of the most well-studied local anaesthetics available. For PE (premature ejaculation) specifically, a 2023 meta-analysis of 11 randomised controlled trials concluded that topical lidocaine was more effective than placebo or most other topical treatments at increasing time to ejaculation.
In delay sprays, you'll typically find lidocaine at concentrations between 7% and 10%. Stud 100, the longest-established UK delay spray, contains 9.6% lidocaine. Promescent - a more premium formulation designed to absorb quickly and reduce transfer to a partner - uses a lower concentration that's optimised for absorption rather than raw strength.
Onset with lidocaine is around 10 to 15 minutes from application. Effects typically last 45 minutes to an hour at normal doses, though this varies between individuals.
One practical advantage of lidocaine sprays: you can dose precisely. Start at one spray, wait, assess the effect, and adjust up from there. This kind of incremental control is harder to achieve with gels or wipes.
Benzocaine: Milder, Slower, More Often Found in Gels and Condoms
Benzocaine is less potent than lidocaine at the concentrations used in consumer products. It's the anaesthetic you'll find in throat lozenges, teething gels, and minor skin-numbing products - and yes, in some delay products.
In the sexual wellness category, benzocaine tends to appear in gel and lubricant formats rather than sprays. The Durex Extended Pleasure range uses benzocaine, as do some delay condoms that have a small amount of anaesthetic built into the tip lubrication. Standalone benzocaine delay sprays are much less common in the UK than lidocaine versions.
Onset with benzocaine is slightly slower - more like 15 to 20 minutes - and the duration tends to be shorter, around 30 to 45 minutes. The milder effect is sometimes exactly what someone wants: a subtle reduction in sensitivity rather than a significant numbing that can feel clinical or distracting.
If you've tried a lidocaine spray and found it too strong even at the minimum dose, benzocaine is a logical next step down.

Which Should You Choose?
The right pick depends on where you're starting from.
New to delay sprays? Start with benzocaine or a low-dose lidocaine spray. Both are forgiving at minimal doses. If you go straight for a high-strength lidocaine product and apply too much, the effect can be more numbing than you bargained for on a first attempt. One spray of a lidocaine product, or a small amount of benzocaine gel, gives you a gentler introduction.
Already tried something and want a stronger effect? Lidocaine is the right direction. Move up to a mid-strength lidocaine spray (7-9% range) and start with two sprays rather than one. Give it the full 10 to 15 minutes to absorb before you assess whether it's working.
Had a lidocaine product and it was too intense? Switch to benzocaine. The milder effect and slightly shorter duration make it easier to manage, and you won't have to worry quite as much about the product transferring to your partner.
Want the most control? Lidocaine spray gives you the best ability to titrate your dose - one spray at a time - and has the strongest evidence base for consistent results.
For most people comparing these two ingredients and deciding on their first delay spray, we'd point you toward lidocaine. It's what the majority of purpose-built delay sprays use, the research backs it up, and you have more flexibility with dosing than you do with a gel.

Using Delay Spray with a Condom
This comes up a lot, and the short answer is: yes, you can use delay spray with a condom - but there's a right way to do it.
The key step is waiting for the spray to dry and absorb before putting the condom on. Apply the spray to the penis, wait 10 to 15 minutes, then put the condom on. This serves two purposes: it gives the anaesthetic time to absorb into the skin so it's actually working, and it prevents the product from sitting between your skin and the condom where it could affect the latex or transfer to your partner.
Most water-based and alcohol-based spray formulas are fine with latex condoms once dry. Some gel-based products contain oils that can degrade latex - always check the product label before using a gel with a latex condom.
The Durex Extended Pleasure condoms include benzocaine inside the tip of the condom itself, which sidesteps the whole issue - the anaesthetic is already on the right side of the latex. That's worth considering if you prefer a simpler approach and don't want to manage timing separately.

FAQ
Is lidocaine or benzocaine stronger?
Lidocaine is stronger at the concentrations used in delay products. A 9.6% lidocaine spray like Stud 100 delivers a noticeably more powerful numbing effect than a 5% benzocaine gel. That's not always a good thing - more potency means more risk of over-numbing if you apply too much, especially on your first try.
Can I use delay spray with a condom?
Yes - apply the spray, wait 10 to 15 minutes for it to absorb and dry, then put the condom on. The wait time is important. It lets the product absorb into the skin rather than sitting on the surface where it could transfer through the condom or, with gel-based products, potentially weaken the latex. Most spray formulas are latex-safe once dry. Always check the product instructions to confirm.
Are there natural alternatives to delay sprays?
A few products use plant-derived numbing agents - clove oil (eugenol) is the most common. These tend to be gentler and shorter-lasting than lidocaine or benzocaine. They're worth considering if you want to avoid pharmaceutical anaesthetics entirely, though the evidence for their effectiveness is less robust. Skins Delay Natural Spray is one option we stock. Beyond topical products, behavioural approaches like the stop-start method or pelvic floor training can also improve ejaculatory control over time without any numbing at all.
Can delay spray transfer to my partner?
It can if you apply it and go straight to sex without waiting. That's why the 10 to 15 minute wait is essential. Once the product has absorbed and dried, the risk of meaningful transfer is very low. Using a condom after the wait period reduces it further. If your partner experiences any numbness, pause and wipe off any residue.
