Question asked by


I've been in a relationship for a while now, and things are great except for one little hiccup: When it comes to sex, I’m finishing way sooner than I want to be. I've been seeing ads for these penis desensitizers. 

They're everywhere—sprays, creams, and whatnot. They claim they can help you last longer by reducing sensitivity, but I’m a bit skeptical.

So, do penis desensitizers actually work?

Penis desensitizers can be an effective solution for treating premature ejaculation. Here’s how they work.

How Do Penis Desensitizers Work?

Desensitizing sprays usually contain an active ingredient like lidocaine, which temporarily numbs the surface of the penis. By reducing sensation, these sprays aim to prolong the time it takes for a man to reach ejaculation.

The best way to think of it is that these agents reduce the intensity of the sexual signal that goes to your brain. This allows for more control over the ejaculatory reflex.


Several clinical studies suggest that desensitizing sprays can be effective in delaying ejaculation. The efficacy varies from person to person, but many men report being able to last longer during sexual activity after using these sprays.

Side Effects

The most common side effect is too much reduction in sensation. It may make getting an erection more difficult and potentially decrease sexual pleasure for you or your partner. 

Some people might also experience skin irritation. It's crucial to follow the product's instructions carefully and perhaps even test it out beforehand.

Additional Points to Consider

  1. Timing: The penis desensitizer usually needs to be applied 5-10 minutes before sexual activity.
  2. Dosage: Apply 3-10 sprays to the most sensitive parts of your penis.
  3. Partner Sensitivity: To avoid transference to your partner, make sure to use penis desensitizers as directed


Other methods to manage premature ejaculation include Kegel exercises, mindfulness techniques, prescription medications, and sex therapy. 

These can be used in conjunction with a desensitizing spray for an even more comprehensive approach.

It’s important to find out the cause of PE to determine the best possible treatment option. As an example, if the condition stems from psychological issues, pursuing sex therapy would likely be the most helpful solution.

In other cases, a man may have a penis that’s more sensitive compared to other men. In which case, a penis desensitizer would possibly be the better solution.


If premature ejaculation is a significant concern, it may be beneficial to consult a urologist or sex therapist for a personalized treatment plan. 

Desensitizing sprays like Promescent Delay Spray can be a viable solution incorporated with a broader strategy that might include behavioral therapy or medications.
