Wan Nai Men's Delay Spray 10ML Gold Upgraded Version is essentially a topical endurance liquid (that is, an external medication sprayed on a localized area to prolong sexual intercourse time). Its mechanism of action is not complicated: through the local anesthetic ingredients it contains (such as plant-based components like clove extract and cnidium extract), it temporarily reduces the nerve sensitivity of the glans surface, slowing down the transmission of stimulation signals, thereby delaying ejaculation. In simple terms, it "desensitizes" the glans.

As a pharmacist, I am often asked at the counter, "How exactly do I choose and use a delay spray?" Today, I'll use the Wan Nai Gold Upgraded Version as an example to explain the usage, safety precautions, and common misconceptions all at once.

1. Ingredients and Mechanism of Action

The main ingredients of Wan Nai Delay Spray include cnidium extract, clove extract, and others. In traditional Chinese medicine, these are commonly used to warm the kidneys and strengthen yang. When applied topically, they produce a mild local anesthetic and warming effect. After spraying, the active ingredients penetrate the surface layer of the skin, acting on sensory nerve endings to reduce their excitability, thereby prolonging the ejaculation latency period (the time from start to ejaculation).

It should be noted that this type of spray only acts locally and does not enter the bloodstream, so its impact on the body as a whole is minimal. However, precisely for this reason, its effect is limited to reducing sensitivity and cannot "cure" premature ejaculation (if premature ejaculation is caused by psychological factors or underlying diseases, you should still see a doctor).

2. Correct Usage Instructions (Step by Step)

1. Timing: It is recommended to spray 20-30 minutes before intercourse. Allowing time for the medication to be absorbed ensures a stable effect.
2. Application Area: Focus on spraying the glans and the coronal sulcus (the groove just below the glans), as these are the areas with the densest nerves and highest sensitivity. If the penile shaft also needs it, a small amount can be applied lightly.
3. Dosage Control: For first-time use, start with 1 spray (approximately 0.1ml), then wait 10-15 minutes to gauge the effect. If it feels insufficient, increase to 2 sprays next time. Do not spray a large amount all at once, as excessive numbness can reduce pleasure or even affect erection.
4. Massage for Absorption: After spraying, gently spread it evenly with your fingers to promote absorption. Wait until it is mostly dry before putting on underwear to avoid rubbing it off and wasting the product.
5. Cleaning Afterward: If your partner will perform oral sex, or if you are concerned about residual medication, it is recommended to rinse with water before intercourse (note: rinsing will weaken the effect, so it is best to rinse right before starting, or simply skip rinsing altogether).

3. Safety Warnings and Contraindicated Groups

Contraindicated groups:

Side effects:
Common side effects include localized numbness, a burning sensation, or mild stinging. If numbness is excessive, difficulty ejaculating or weakened erections may occur. A small number of people may experience allergic reactions such as redness, swelling, or itching, in which case use should be stopped immediately and the area washed.

5. Frequently Asked Questions (FAQ)

Q: Can Wan Nai Delay Spray cure premature ejaculation?
A: No. It only temporarily reduces sensitivity, treating the symptom rather than the root cause. If premature ejaculation is psychological, sexual counseling may be needed; if it is caused by a medical condition (such as prostatitis), the underlying disease must be treated.

Q: How long does it take to work? How long does the effect last?
A: It typically takes effect within 20-30 minutes, and the effect lasts 1-2 hours, varying from person to person. It is recommended to try it in advance to find the right dosage and timing for yourself.

Q: Can it be used every day? Will it cause dependence?
A: Daily use is not recommended. Frequent use may lead to local skin tolerance or reduced sensitivity, but this generally recovers after stopping, and it is not addictive. It is best to use it only when needed and combine it with exercises (such as Kegel exercises) to address the underlying issue.

Q: What should I do if I feel numbness during use?
A: Numbness is normal and indicates the effect is strong. Next time, reduce the dosage, or wait longer after spraying before washing off part of it. If numbness is severe enough to affect erection, wash immediately and reduce the amount used.

Q: Can it be used together with oral medications (such as Viagra)?
A: Yes, but with caution. Topical sprays and oral medications work through different mechanisms and theoretically do not conflict, but both have blood pressure-lowering effects, and combining them may cause dizziness. It is recommended to use them separately or consult a doctor.

6. Pharmacist's Summary

Wan Nai Men's Delay Spray 10ML Gold Upgraded Version, as a topical endurance liquid, is suitable for men who occasionally need to prolong intercourse. Remember three key points: start with a small amount, spray in the right position, and avoid the urethral opening. If persistent discomfort occurs, stop using it and seek medical attention.

If you are still undecided about which product to choose, you can refer to the comparison between Wan Nai Delay Spray and German Black Diamond, or check out the 2H2D Platinum Delay Spray Buying Guide and the Japanese Black Panther 4th Generation Ingredient Analysis.

One final reminder: if premature ejaculation is severe or persistent, don't rely solely on sprays—visit the andrology department at a reputable hospital. If you have any questions about medication, feel free to ask your pharmacist.
