There are many brands of topical delay products, and choosing the wrong direction not only wastes money but may also affect the experience. This article compares four popular products—BOSO, Wannai, Black Diamond, and Green Knight—across five dimensions: ingredients, onset time, duration, side effects, and price, to help you decide based on your needs. BOSO is suitable for beginners seeking gentle anti-sensitivity, Wannai for experienced users seeking strong effects, Black Diamond for those with ample budget and requiring no numbness, and Green Knight for those who like to prepare in advance and prioritize their partner's feelings.
There are more and more external endurance products on the market, but many users report that some only cause numbness, some have short-lasting effects, and others require waiting a long time after spraying. Which one is right for you? This time, I selected four representative products—BOSO Delay, Wannai Delay, Black King Kong, and Green Knight—and broke them down from five core dimensions to help you find the best match.
1. Ingredients and Mechanism of Action
BOSO Men's Delay Spray: Features a desensitizing formula with plant extracts like Cnidium, clove extract, and Sarcandra glabra. It works by gently reducing the sensitivity of the glans surface to prolong ejaculation time, without alcohol or strong anesthetics, resulting in minimal numbness.Wannai Delay Spray: A classic model with similar ingredients but adds ethanol as a penetration enhancer for faster absorption. It also contains a small amount of anesthetic (e.g., benzocaine analogs), offering rapid onset but potentially more noticeable numbness.Black King Kong Endurance Liquid: A German brand claiming "no numbness, no side effects." Its ingredients are mainly tocopherol and plant essential oils, with a mechanism focused on physical coverage and microcirculation promotion. The official instructions say it takes effect just 8 minutes after spraying, making it extremely fast.Green Knight II Endurance Liquid: An upgraded deluxe version with a pure plant formula, emphasizing gentle and lasting effects. It requires spraying 20-30 minutes in advance, with effects gradually appearing, making it more suitable for users who are not in a hurry.2. Onset Time
BOSO: Recommended to spray 15-20 minutes before intercourse, evenly applying to the glans and coronal sulcus. First-time users should start with a small dose, with effects gradually noticeable after about 15 minutes.Wannai: Ethanol penetration allows for faster absorption, typically taking effect within 10-15 minutes. Suitable for spontaneous situations, but dosage needs to be controlled to avoid excessive numbness.Black King Kong: Officially claims 8-minute onset; in practice, a slight warming sensation is felt around 10 minutes, followed by reduced sensitivity. It is the fastest among the four.Green Knight: Requires longer preparation time, reaching peak effect in 20-30 minutes. Best for planned scenarios; last-minute use may yield diminished results.3. Duration and Effects
BOSO: Single-use effects last about 30-60 minutes, significantly improving control and reducing urgency without affecting erection hardness. Suitable for most moderate-duration needs.Wannai: Lasts about 30-50 minutes with strong effects and noticeably reduced sensitivity. However, some users report a "film-like" sensation on the glans, with diminished pleasure.Black King Kong: Relatively longer duration, about 40-60 minutes. Due to the absence of strong anesthetics, pleasure is well-preserved, but the price is higher.Green Knight: Lasts about 20-30 minutes with mild effects, offering slight prolongation. Not suitable for those seeking significant delay; better for mild premature ejaculation where "just a bit longer" is desired.4. Side Effects and User Experience
BOSO: The desensitizing design makes numbness very mild, with rare burning or stinging. It does not affect oral sex after washing, making it very beginner-friendly.Wannai: Some users report slight burning or tingling, especially when sprayed undiluted. Numbness is more noticeable, and residue may still affect partner sensation even after washing.Black King Kong: Officially emphasizes no numbness, and in practice, it rarely occurs. However, a few people may experience warmth or slight redness, possibly related to individual skin sensitivity.Green Knight: Almost no numbness, but effects can be inconsistent. Some users feel no difference after use, requiring multiple attempts to find the right dosage.5. Price and Cost-Effectiveness
BOSO: Mid-range positioning, with a single-use cost of about 25-40 RMB. The desensitizing formula justifies the premium, offering good overall value.Wannai: Moderately priced, about 20-35 RMB per use. A classic volume seller, but the impact of numbness on experience should be considered.Black King Kong: An imported brand, costing about 50-80 RMB per use. Higher price, suitable for users with ample budget who prioritize a numbness-free experience.Green Knight: Mid-to-high price range, about 30-60 RMB per use. Packaging is upgraded, but effects are average, making it better as a backup option.6. Scenario-Based Recommendations
First-time users or those with sensitive skin: Choose BOSO. The desensitizing formula makes it hard to go wrong, with satisfactory effects and almost no numbness—a safe entry-level choice.Those seeking fast, strong effects: Choose Wannai. Quick onset and powerful effects, but be willing to accept some numbness. Refer to Wannai Usage to avoid over-spraying.Users with ample budget requiring no numbness: Choose Black King Kong. Good pleasure retention, ideal for those with high expectations for sexual experience quality.Those who like to prepare in advance and focus on partner comfort: Choose Green Knight. Gentle and non-numbing, but requires patience in adjusting dosage. It's recommended to combine with Seikei Pitfalls for precautions.Additionally, if you want a stronger effect, consider Iluce 101, an imported German formula with more prominent endurance and a higher price, suitable for brand-conscious users.
Conclusion: There is no "best" product, only the most suitable solution for you. First, clarify your needs—whether it's a first attempt, a pursuit of strong effects, or a focus on a numbness-free experience—then match them with the table and scenarios to avoid wasting money and achieve a satisfying experience.
help常見問題
Q1.Which one is less numbing, BOSO Men's Delay Spray or Wannai?
BOSO is designed with a desensitization-resistant formula, resulting in a milder numbing sensation, making it suitable for beginners. Wannai contains alcohol and a small amount of anesthetic ingredients, leading to a more noticeable numbing effect. If you prioritize preserving sensation, BOSO is the preferred choice.
Q2.Should I wash off the topical delay spray after applying it?
Most delay sprays need to be absorbed before washing off to avoid affecting the effect. For BOSO and Green Knight, it is recommended to rinse with clean water 15-20 minutes after spraying. For Wannai and Black Diamond, follow the instructions. Generally, some effect can still be maintained after washing.
Q3.Why do I feel no sensation and take even longer after using Wannai spray?
It may be due to excessive dosage causing over-numbing of the glans, making it difficult to reach orgasm. It is recommended to start with 1-2 sprays and gradually increase the dosage. If you still feel insensitive, switch to milder products like BOSO or Black Diamond.
Q4.Is the 8-minute effect of Black Diamond real? Can beginners use it?
Officially, it claims to take effect in 8 minutes, but in actual experience, most people find it effective in 10-15 minutes. Beginners can use it, but due to its strong effect and high price, it is recommended to try a small dose first to avoid waste or discomfort.
Q5.Will topical delay sprays affect my partner's health?
Regular products (such as BOSO, Wannai, Black Diamond) mostly contain plant extracts or externally safe ingredients. After absorption and washing, very little residue remains, usually not affecting the partner. However, if the partner has a history of allergies, it is recommended to test on a small area first or rinse thoroughly.
