What Exactly Is Louis 16 Endurance Spray? Male Delay Spray, Prolongs Intercourse Time, Adult Novelty Product?

Louis 16 Endurance Spray (Loui's 16) is a topical delay spray, classified under topical endurance liquids. Its core function is to reduce the sensitivity of the glans penis, prolong the ejaculatory latency period, and allow men to maintain longer during sexual activity. The product claims to be derived from an ancient European formula, but uses modern processes to extract active plant ingredients.
Analysis of Main Ingredients (Based on product packaging and instructions)
These ingredients work together to form a temporary "protective film" on the surface of the glans, slowing down nerve conduction velocity, thereby prolonging the time to climax. Note: This is surface anesthesia, not a systemic effect, and does not affect erectile function.
Dosage and Administration: How to Use It Effectively?
1. Preparation before use: First, wash the penis with warm water and dry it. For first-time use, it is recommended to test one drop on the inner forearm and observe for 20 minutes for any allergic reaction.
2. Spraying method: Point the nozzle at your finger (not directly at the glans), spray 1-2 times, then use your finger to apply evenly to the glans, corona, and frenulum area. Avoid spraying the urethral opening, as this can cause stinging or urinary discomfort.
3. Waiting for effect: Wait 10-20 minutes after application for the ingredients to be fully absorbed. You can put on underwear during this time to prevent rubbing it off. Normal sexual activity can proceed afterward.
4. Dosage adjustment: Start with 1 spray. If the effect is insufficient next time, increase to 2 sprays. Generally, do not exceed 3 sprays. Overdosing can lead to numbness of the glans and loss of sensation.
5. Cleaning: If oral sex is desired, it is recommended to wash off the surface residue with clean water. The product instructions state it does not affect oral sex, but washing it off is safer in practice.
Special Reminder: Do not mix with German Black Diamond Endurance Liquid Male Anti-Premature Ejaculation Delay Spray Non-Numbing No Side Effects Hong Kong Version, as the ingredients may overlap and cause excessive numbness.
Effects and Sensations: How Long Can It Prolong?

According to product instructions and most user feedback, ejaculation time can be extended by 20-30 minutes after use, roughly doubling or more. However, actual results vary by individual:
It's important to clarify: It is not a "miracle drug" and cannot cure premature ejaculation itself; it only temporarily reduces sensitivity. The effect disappears upon discontinuation.

Comparison with Other Delay Products

Topical endurance liquids on the market are mainly divided into two categories:
1. Anesthetic type: Such as Louis 16, German Black Diamond, EROS Ilus, etc., containing lidocaine, benzocaine, or plant anesthetics. They work quickly but may cause numbness.
2. Non-anesthetic type: Such as some erection-enhancing delay liquids containing plant extracts (e.g., ginseng and epimedium), which improve control mainly by enhancing blood flow, but work slower.
Louis 16 belongs to the plant anesthetic type, which is milder than chemical anesthetics (like lidocaine), but the principle is the same. In comparison, German Import EROS Ilus 101 Male Endurance Liquid Super Delay Authentic with Anti-Counterfeit Verification contains lidocaine, offering stronger anesthetic effects but potentially more noticeable side effects.
Selection Advice: If sensitive to chemical anesthetics, opt for plant-based formulas like Louis 16; if a stronger effect is preferred, try EROS, etc.
Real Experience Reference: One user shared that after using German Diamond Endurance Cream for a month, they found the plant formula more suitable, without numbness. See details in After Using German Diamond Endurance Cream for a Month, Sharing My Real Experience - mqqu4fxl1.
Additionally, the user experience of trying BOSO Delay Spray after age 30 is also worth referencing, see After Trying BOSO Delay Spray at 30, Sharing My Real Feelings - mqtozvpv1.
Frequently Asked Questions (FAQ)
Q: Will Louis 16 Endurance Spray affect erections?
A: No. It only acts on the surface of the glans, does not enter the bloodstream, and does not affect corpus cavernosum engorgement. However, if you are nervous or overly worried, psychological factors could lead to erection difficulties.
Q: How often can it be used? Can it be used daily?
A: Daily use is not recommended. Do not exceed 3 times per week. Frequent long-term use may decrease glans sensitivity, and discontinuation could lead to "rebound sensitivity." It is better suited for on-demand use.
Q: Does it need to be washed off immediately after spraying?
A: No. After waiting 10-20 minutes for full absorption, you can gently wash off surface residue with water, and the effect remains. If not washed off, the effect lasts longer but may leave a residual taste.
Q: Can it be used with condoms?
A: Yes, but it is recommended to apply and let it dry before putting on the condom. Oily ingredients may weaken the strength of latex condoms, increasing the risk of breakage. It is advisable to use water-based lubricants in conjunction.
Q: Why do I still have premature ejaculation after using it?
A: Possible reasons: 1) Insufficient dosage; 2) Insufficient waiting time; 3) Spray not fully absorbed; 4) Mainly psychological factors. Try starting with 2 sprays and waiting a full 20 minutes. If still ineffective, consider whether there are other physiological issues, such as prostatitis, and seek medical diagnosis.
Q: Can it be used on a partner?
A: The product instructions mention it can "enhance female vaginal pleasure," but in practice, it reduces female sensitivity, leading to decreased pleasure. Direct use on women is not recommended.
Summary and Recommendations
Louis 16 Endurance Spray, a male delay spray for prolonging intercourse time and adult novelty use, as a topical endurance liquid, is suitable for men who ejaculate too quickly due to high sensitivity.

If you have high blood pressure, heart disease, or are taking other medications, consult a professional physician or pharmacist before use. Discontinue use immediately if any discomfort occurs.
