Dynamo Delay is a strong lidocaine spray, intended to help men who have a problem with premature ejaculation.
Testing desensitizing products is one of the main topics I write about on this site. So I have a very clear idea about what makes the good ones effective, and the bad ones slightly scary.
In the case of Dynamo, I thought it was one of the better sprays I’ve tried. However, there are a couple of important points to bear in mind if you plan on using it.
So in this review, I’ll describe how it worked for my partner and I. And also some key information to help you use it correctly and safely.
Who makes it?
Dynamo is made by the adult sex toy company Screaming O, which is based in the United States. They pride themselves on having won awards for some of their sex toys.
Very few of these sprays are made by pharmaceutical companies. So it’s at least reassuring to know there’s a company you can contact with questions.
I got in touch to find out more about the spray and found they were helpful and friendly to communicate with.
It’s also worth noting that Dynamo is FDA compliant, which means the manufacturer has tried to make it responsibly.
The active ingredient is Lidocaine USP 13%. That translates as approximately 10 mg per spray.
Interestingly, this makes it the highest concentration of lidocaine I’ve seen in a spray. The company suggests that means you’ll get more in the bottle.
To me, it also increases the risk of over-numbing, which I’d be looking out for.
The inactive ingredients listed are:
- Isopropyl Palmitate
- SD Alcohol 40B
- Stearic acid
How to use Dynamo Spray
The package has the following instructions:
Apply three or more sprays, not to exceed 10, to head and shaft of penis before intercourse, or use as directed by a doctor…Wash product off after intercourse.
There are some more instructions on the website. They recommend waiting 5 to 10 minutes before having sex. And to wipe with a damp cloth if you plan to have oral sex.
My tips for using the spray
Over the years, I’ve developed a more cautious approach to using delay sprays. Here’s what I’d do:
- Spray your forearm once and wait to see how your skin reacts.
- Just use 1 spray first time, and only on the penis head.
- Wait for 5 to 10 mins and then wash off any residue with a damp cloth or shower if you plan on having oral or unprotected sex.
- Wash your hands too so you don’t get it in the eyes etc
- Wash after having sex.
- Decide next time if you need 2 or more sprays, and if you want to apply to the shaft as well as the head.
My experience using Dynamo
My first impression is that they used the exact same bottle as Promescent. It’s the same size, has the same child safety lock and a similar metered pump.
At the end of the day though, it’s good it has that safety lock. And the metered pump is much better than the aerosol sprays, as it’s easier to apply the same dosage each time.
I ignored the 3 sprays instruction and started with 1 as always. It’s usually enough for me anyway and I don’t like being so numb it only feels like I have half a penis. You’ll know what I mean if you apply too much…
There was no noticeable smell, which is a plus. And the spray was easy and quick to massage into the skin, without leaving a sticky residue. So far so good.
5 mins later and I could already feel it taking effect. 10 mins later after a quick wipe with a cloth, I called my partner into the bedroom.
We started with oral sex, which is an important hurdle not all sprays pass. Dynamo was fine though – only a slight chemical smell, which is as good as it gets, and no transference to her mouth.
I was definitely feeling numb on the penis head. And after some foreplay, we moved on to sex.
Longer lasting sex
As is always the way with these sprays, the pleasure was definitely reduced somewhat – especially on the penis head.
But the sensitivity was also significantly calmed. That meant I felt in good control, and was able to last a fair bit longer.
I don’t time sprays these days – experience has taught me that it just works or doesn’t. But even if it helped me last 5 mins longer, for you it might be 1, 2 or 10 – there’s just no way to tell.
So really, the effect was good enough for me. Yes, it reduced some of the pleasure. But it left me with enough sensation to enjoy sex, and last longer.
Finally, the numbing lasted around 1.5 hours before slowly wearing off over the next 30 minutes.
With 1 spray, I did have some tingling sensation, but it wasn’t that bad, and not as noticeable as some other sprays which actively burn.
The next day I tried with 3 sprays, and found that was way too much for me. The tingling feeling increased to an uncomfortable level, I found it difficult to get an erection, and had zero sensation where I’d sprayed it.
So as always, I recommend erring on the side of caution. Start with 1 or 2 sprays and only add more the next time if you feel you need more numbing.
- Strong numbing, which some men will prefer.
- Works fast – just 5 to 10 minutes.
- Has a metered pump to help you apply the same amount every time.
- Absorbs well without leaving a sticky residue.
- Can be used with oral sex, and with or without a condom.
- It’s made to be FDA compliant.
- With the right dosage, you can still feel enough sensation to enjoy sex, but with more control.
- Relatively low price, with many sprays per bottle (though to be fair, each spray seems quite small).
- As is the case with all desensitizing products, it doesn’t cure premature ejaculation.
- There’s a faint chemical smell.
- The high dosage of lidocaine means that if you apply too much, it can make it difficult to get an erection or enjoy sex.
- Produces a tingling sensation, which might be unpleasant for men who are more sensitive to lidocaine.
If you’re looking for a cost-effective and strong delay spray, I think Dynamo Delay is a good choice.
If you find these type of sprays work for you, but only if you apply a ton of it, then Dynamo’s stronger formula might help you save some money in the long-run.
However, if you’re sensitive to lidocaine, and ever have difficulty getting an erection because of feeling too numb, then it perhaps isn’t right for you.
On the whole, my partner and I were quite impressed with how it worked. It’s particularly good that there’s only a faint smell and taste, so if you’re into oral sex, it won’t ruin the fun.
