This Japanese NASKIC Naishiwang long-lasting spray is a popular topical long-lasting liquid, and its principle is to temporarily reduce local sensitivity through skin-absorbed local anesthetic ingredients. It is suitable for people who want to prolong intercourse time but do not want to take oral medication, but the usage and timing of cleaning are crucial. This article explains the ingredients, usage steps, comparison with similar products, and safety contraindications one by one, helping you determine whether it is suitable for you.
What It Is and How It Works

Japan NASKIC NASHI KING long-lasting spray belongs to the category of men's topical endurance liquids. Its approach is not complicated: after spraying on the glans and coronal sulcus area, the local anesthetic ingredients in the formula (commonly lidocaine, benzocaine, and similar) are absorbed through the skin and mucosa, temporarily reducing the sensitivity of local nerve endings, allowing the ejaculation reflex to come more slowly, thereby prolonging intercourse time.
It should be noted that this type of product "reduces sensitivity," not "treats premature ejaculation." If you have primary premature ejaculation or accompanying erectile problems, a spray alone cannot solve the root cause, and a doctor's evaluation is needed.
Ingredient Analysis: What Each Ingredient Does
The formula of topical endurance liquids generally falls into three parts: the active, the auxiliary, and the skin-feel adjusters. Based on product descriptions and similar formulas for reference:
Key point: The speed of onset and degree of numbness depend on the concentration of local anesthetic ingredients and how long you leave them on the skin. This is also why "how long to wait after spraying" and "whether to wash it off" affect the experience more than "how many sprays."
How to Use: Steps and Timing Matter More Than Dosage

According to product instructions and common clinical usage, it is recommended to operate as follows:
1. Start with 1-2 sprays for the first time, spray on the glans and coronal sulcus; do not start with four or five sprays. For most people, 1-2 sprays are enough; spraying too much causes excessive numbness, which instead affects erection and pleasure.
2. Use about 15-30 minutes in advance, allowing time for skin absorption. Spraying and immediately having intercourse often yields unsatisfactory results.
3. After spraying, decide whether to wash based on product instructions. If the formula requires washing, rinse off surface residue with warm water before intercourse, which can reduce the chance of your partner also experiencing numbness; for products that do not require washing, wait for absorption according to instructions.
4. It is recommended to use with a condom, which both reduces numbness for both parties and lowers the risk of local irritation.
5. Do not use with oral delay medications or alcohol. Alcohol will aggravate numbness and dizziness, and stacking with oral medications may reduce sensitivity too much.

How to Choose Among Similar Products
The differences among topical endurance liquids mainly lie in onset speed, numbness intensity, and washing requirements. Here is a dimensional comparison of several common products (not laboratory data, but a comprehensive summary of product descriptions and usage feedback):
The selection logic is simple: for first-time use and fear of numbness, choose a mild or controllable option; after several uses and knowing your tolerance, consider higher intensity.

Safety Warnings: Who Should Not Use It

Topical use does not mean no risk; the following points must be made clear:
Regarding side effects, clinically common ones are brief burning, redness, or relatively strong numbness, which generally gradually subsides after washing. If numbness affects erection, it means you sprayed too much; reduce the amount next time.
Common Questions
Why is there no effect after spraying?
Most likely you had intercourse immediately after spraying without waiting for absorption, or the spray position was off. Using 15-30 minutes in advance and aiming at the coronal sulcus area is more effective than increasing the dose.
Can it be used every day?
Long-term high-frequency use is not recommended. It is a tool for temporarily reducing sensitivity; frequent use may cause local skin tolerance and worsen the experience. Use as needed.
Can it be used together with oral delay medications?
Do not stack them on your own. The two have different mechanisms, and stacking increases the risk of numbness and dizziness; medical guidance is needed.
The above usage and contraindications are based on product descriptions and general principles for similar topical endurance liquids. Everyone's skin tolerance is different; for first-time use, be sure to try a small amount. If you are taking medication or have underlying diseases, consult a physician or pharmacist before use, and do not increase the dose on your own.
helpFAQ
Q1.Does Naishi Wang spray need to be washed off after spraying?
Check the product instructions. For formulas that require washing, rinse off surface residue with warm water before intercourse to reduce numbness for your partner; for those labeled no-wash, follow the instructions and wait for absorption. Either way, it is recommended to use a condom to reduce the risk of irritation for both partners.
Q2.How many sprays of delay spray are appropriate?
The first time, start with 1-2 sprays on the glans and coronal sulcus. Too many sprays will cause excessive numbness and affect erection and pleasure. If the effect is not good, adjust the timing and location first, and do not blindly increase the dose.
Q3.Can topical delay liquid and oral delay medication be used together?
It is not recommended to stack them on your own. The two have different mechanisms, and stacking increases the risk of numbness and dizziness, and sensitivity may drop too low. If a combination regimen is needed, have a doctor or pharmacist evaluate it first.
Q4.Will the partner feel numb after I spray delay spray?
Possibly. Residual ingredients contacting the partner's mucosa can cause local numbness. Washing after spraying or using a condom can significantly reduce this. This is also why it is recommended to control the spray amount and timing of washing.
Q5.Can delay spray still be used if the glans is slightly broken?
No. When the mucosa is broken, absorption speeds up, numbness and stinging will be amplified, and the risk of infection also increases. Wait until the broken skin heals before considering use; if there is inflammation, see a doctor first.
Q6.How to choose between Naishi Wang and GOD OIL Generation 2?
If you are afraid of numbness and want to preserve pleasure, prioritize GOD OIL Generation 2, which focuses on not causing numbness; if it is your first time and you want controllable numbness, choose a medium-strength product such as Naishi Wang. After using it a few times and understanding your tolerance, adjust accordingly.
