Our Prolong Review Summary

Prolong is both a device and a training program developed by psychiatrists at InnovaDerma, a global health and life sciences company. However, to sound less “sciency” and more accessible, it’s marketed under the Smiling Dick company.

The device has been specially designed to treat premature ejaculation by Dr Andy Zamar, Medical Director and Founder of The London Psychiatry Centre.

Prolong FDA approved vibrator has a 3-volt motor embedded into a textured and curved silicon device. The vibrator comes with a training program and a bottle of lubricant. The program combines the stop-start masturbation technique with the use of a vibrator.

In short, you have to masturbate with the vibrating silicon device during a six-week program. Doing so will desensitize your penis and slow down your ejaculation response.

Two different studies1,2 have shown that Prolong can make you last longer in bed. By using the device along with the training program, most participants in both studies improved their ejaculation latency.

What is Prolong?

Prolong is not your usual treatment for PE, nor is it your ordinary bedside toy – it’s a combination of both. Developed by leading psychiatrists at InnovaDerma, a global health, and life sciences company, the product consists of a vibrating device that is designed to be used on a six-week “climax control training program”. And by training, we mean masturbating.

Both the device and program have been clinically proven to help treat premature ejaculation in two independent studies. We elaborate more on these below. It’s also the first device and training program to receive FDA approval – a big tick from the world’s largest food and drug administration body.

How Does Prolong work?

The device works by simply placing it under the head of the penis and gently applying pressure as you masturbate. Through using the stop-start technique – the method of edging towards an ejaculation but withholding – the vibrating device works to reduce oversensitivity in the penis.

Prolong users are instructed to train for three sessions a week over the duration of the program. This can be done with a partner if you’re looking to shake things up, alternatively, it can be done solo.

Personally, I would advise doing the first sessions alone if you suffer from severe PE. As we explain on the Cum too Fast page, ejaculation can be triggered by two things: physical arousal (genital stimulation) or psychological arousal (how aroused you feel). By starting the program alone, you can isolate the physical aspect. When you’re familiarised with Prolong new sensations, you can then introduce your partner to your session and switch from a training mindset to a funnier vibe (pun intended!). 

Whatever approach you take, Prolong says you can expect to see gradual and lasting gains over the course of the program – both in the time taken for you to ejaculate, as well as your overall confidence.

Does Prolong really work?

Two different clinical studies back Prolong’s efficacy. In the first, the device showed an IELT increase of 11-fold in 61% of men1. An 11-fold increase means that a man who lasted 1 minute was shown to increase to 12 minutes. As noted, this increase occurred for the majority of the study’s participants.

The second study showed more modest results. Patients had a pre-treatment average of about 1.5 minutes (87.91 seconds). Six months after treatment, their average was over 3 minutes (201.78 sec.)2. It is important to note that the standard deviation of the results was high. In other words, Prolong can do wonders for some, while the impact can be less significant on others.

About Prolong Study

While the exact impact of Prolong varies across these two studies, they both support the claim that the device and program are shown to extend a man’s time to ejaculation. Since premature ejaculation has a lot of different causes, it’s normal to see variability in the results.

It’s still important to note that the sample size of both studies is small. So, even if we can assume that Prolong does work, it would be helpful to see further large-scale studies.

Nonetheless, it’s worth emphasizing that if you buy Prolong from its official website, you have a 100% money-back guarantee. So, if the device doesn’t work for you, you can always ask to be reimbursed for your purchase.

Regular Stop-Start Method vs. Prolong

Although Prolong training is based on the stop-start method, the added effect of using the Prolong device is significant (according to one of the studies).

The first study that examined Prolong showed an 11-fold increase in 61% of subjects. This study compared the efficacy of Prolong to another group of patients that had a series of sex therapy sessions (cognitive-behavioral therapy). In the sex therapy group, the increase was 3-fold in only 40% of the subjects.

So, even if more studies would be needed to pose a conclusion, Prolong appears more effective than traditional masturbation exercises alone.

Is Prolong safe to use?

Prolong has met all the FDA safety requirements. The FDA has to approve every medical device that is sold in the US. It also comes with zero side-effects, which sets it apart from many other medications on the market.

How to Use Prolong?

You have to use Prolong three thirty-minute sessions a week for six continuous weeks.

Prolong comes in a box with a water-based lubricant. First, you need to apply lubricant on your frenulum, on your penis head (glans) and under the penis head at the top of your shaft. If you’re not circumcised, you should apply lubricant on your foreskin too.

When everything is well lubricated down there, you can take the vibrating device in your hand and cup it under your penis at the frenulum level. After that, you simply turn the device on and start masturbating as you would normally.

The vibrations should make you want to come quicker than usual. The stop-start technique works by edging yourself towards an ejaculation very gradually. So, as soon as you feel you’re going to come, pull back and wait until the urge has passed. Once you no longer feel the need to ejaculate, resume the stimulation.

Prolong users are advised to repeat this exercise three times before allowing themselves to ejaculate.

My Experience with Prolong

Before I start, I just want to clarify some things. I’ve already followed cognitive-behavioral therapy for premature ejaculation (with limited success). Also, I’m currently on a low dosage of SSRI, so this might affect how I react to Prolong. More importantly, my personal experience with Prolong isn’t necessarily representative of what yours will be.

Still, I’m curious to know how much the vibrating aspect of the therapy could help to reduce oversensitivity and gradually build resistance.

Personally, I find that local numbing agents like lidocaine sprays work well on me. Even if I’m a big fan of products like Promescent, I must admit that it’s not always convenient to use. If Prolong does works for me, I won’t be nearly as reliant on my spray bottles given the product’s claimed lasting impact.

Week 1

The device is very easy to use and “Smiling Dick”, Prolong’s brand platform offers a useful step-by-step guide. Anyhow, the procedure is straightforward. Apply some lube, masturbate using the device, stop before you come. Repeat.

The vibrating sensation does make you come faster than normal. Prolong studies tell us that you should begin to see an improvement from the first week. So, I’ve timed all my sessions to know how much time it takes me to reach my point-of-no-return. Indeed, I saw a minor improvement over the course of the first week. As Prolong states, the changes are incremental.

Week 2

The first week was more about getting used to the vibrating feeling. Like a lot of other premature ejaculators, I’m fairly sensitive to genital stimulation. Even when it occurs in a non-arousing context, physical stimulation alone makes me reach my point-of-no-return quickly

This has reduced now that I’m taking an SSRI (a form of antidepressant). Still, during the first week of the program, even when I was doing a session with no erotic thoughts at all, I wouldn’t last too long.

The second week is where progress really kicked in. As I mentioned, I time every session. During my first three sessions, it took me around two to three minutes to reach a point close to my point-of-no-return. Now, I can last up to five or six minutes.

Again, during those sessions, I’m 100% focused on the physical sensations. I’m not allowing myself to have erotics thoughts. My goal is to see how long I can last with genital stimulation alone.

Now, I just want to stress that time shouldn’t be the final goal here. Of course, it’s encouraging to see measurable progress. And let’s be honest, if you’re doing this kind of therapy, it’s because you want to last longer.

However, there are three different components to PE: time, control and satisfaction. Our ultimate goal should always be satisfaction. How long you last is only relevant as long as it helps us to enjoy sex better. The same goes with control. I’m timing myself just because I want to give you the most reliable review of Prolong. Still, I think it’s important to not obsess over time.

That’s why I’m not timing myself when I’m with my partner. When I’m with the person I love, I want us to have a good time. I’m focusing on the experience, not on “performance” or any other stressing thoughts.

Speaking of sex with a partner, I can say that I did feel a bit more in control than usual during intercourse. However, I can’t say if it’s purely the effects of using Prolong at this stage.

Again, I don’t have a baseline for comparison. More importantly, control varies from time to time, and it depends on a lot of factors. I would need to do more “testing” to have a better idea.

This section will be updated each week until I complete the 6 weeks program.
