Hello everyone, I'm Lao Zhang, an ordinary working man in my late thirties. I've been grinding away in the IT industry, where overtime is a regular occurrence. With all that pressure, my physical condition started to decline. A couple of years ago, I noticed I was struggling a bit in my marital life, especially when it came to stamina—it always felt like something was missing. My wife never said anything, but deep down, I felt a bit insecure.
At first, I tried some so-called "nourishing" health supplements. After a month or two, I realized they were just a psychological placebo—no real effect. Later, on some men's health forums, I saw many people recommending delay sprays, especially mentioning the Japanese brand Kurohyo, saying it was a topical endurance spray with relatively lower risk. With a "why not try it" mindset, I looked it up online and found that the Kurohyo II, a Japanese-imported male endurance delay spray for premature ejaculation, had pretty good reviews, so I ordered a bottle.
My First Attempt: A Mix of Nerves and Surprise
The product arrived in about two or three days—a small 10ML bottle, quite refined. For the first use, I strictly followed the instructions. It was a weekend, about an hour after dinner. I took a shower first, then gently pressed the nozzle once on the glans and the coronal sulcus area, spraying one time. The instructions said 1-2 pumps were fine, but I played it safe and went with one. After spraying, I used my fingertip to massage it lightly so the liquid would absorb evenly. About five minutes later, I felt a slight warmth on the glans, which gradually turned into a mild numbness—not the kind where you lose all sensation, but more like a dulled feeling.
The instructions said it takes effect in 30 minutes and peaks at 60 minutes. I waited about 40 minutes before starting. Honestly, that night's performance surprised me. Normally, I'd last maybe five or six minutes, but this time I felt I lasted at least 15 minutes, possibly even longer. Throughout the whole process, I could still feel pleasure—just with reduced sensitivity, so I had better control. Afterward, I could clearly feel my confidence returning.
Follow-Up Usage Summary: Lessons from Trial and Error
Over the next few months, I used it several more times. I found that this Kurohyo really requires some experimentation to find the method that works best for you.
* Onset Time and Dosage: I found that one spray was already effective for me, and I could usually feel the effect after waiting 30-40 minutes. If I sprayed twice, the numbness was stronger, but the delay effect was also more pronounced—reaching 20 minutes or even longer—though the pleasure was further reduced. I personally prefer one spray to strike a balance between effect and sensation. The onset time varies greatly depending on individual constitution and absorption. Once, I felt it after just 25 minutes, and another time, it took nearly 50 minutes to reach optimal effect.
* Numbness: This is a common issue with this type of topical endurance spray. The first time, the numbness felt unfamiliar—a bit like being under anesthesia. But after three or four uses, my body seemed to gradually adapt, and the numbness became less intense, or I got better at managing it. However, if you're chasing peak pleasure, this numbness does take something away.
* Washing: The instructions said it can be washed off after 30 minutes without affecting efficacy. I tried it a few times, and that was indeed the case. If oral play is on the table, washing is more reassuring since it's a topical product. That said, washing does slightly reduce the effect, but the impact is minimal. My routine is to spray, wait about 15-20 minutes for absorption, then rinse off in the shower before starting.
Drawbacks and Inconveniences I Have to Mention
After using it for so long, beyond the effects, I've also noted some aspects I'm less satisfied with:
1. Reduced Pleasure: This is the most obvious downside. While the delay effect is significant, the drop in sensitivity does diminish that "explosive" sensation at climax. It was especially noticeable when I first started using it. It got better after I got used to it, but if you're after pure, raw pleasure, this might not be the best choice.
2. Preparation Time: This product doesn't work instantly—you need to spray, massage, and wait for absorption, which requires at least 30 minutes of lead time. That means you can't be too spontaneous; you have to plan ahead, which can sometimes be a bit of a mood killer. For example, a sudden urge hits, and then you realize you have to wait half an hour, and half the excitement fades.
3. Concerns About Dependency: Even though it's topical, long-term use makes me worry about psychological dependence. I feel like if I don't use it, I'll just revert to my old state. So, I don't use it every time—I save it for key moments and try to regulate myself through exercise and meditation in daily life.
A Brief Comparison with Other Products
Before choosing the Kurohyo II, I also looked into some other options, like the same brand's Kurohyo III and Kurohyo 4, as well as sprays from other brands. I won't go into too much detail here, but let me briefly share the differences I learned about:
* Kurohyo Series Upgrades: From what I understand, the later Kurohyo versions focus more on gentler ingredients while optimizing onset speed and reducing numbness. For instance, the Kurohyo 4 may claim faster onset and less numbness, but the price is usually higher. I chose the II mainly for its cost-effectiveness, and as an entry-level option, I wanted to test the waters first.
* Maruto Spray: I also read some reviews of the Maruto spray, which is another popular Japanese brand. It's said to have fast onset and relatively mild numbness, but the price is generally higher than the Kurohyo series. The ingredients may also differ—Kurohyo II emphasizes plant extracts, while Maruto might lean more toward pharmaceutical components. It really depends on the specific formula.
* Price and Ingredients: Overall, when choosing an endurance spray on the market, you need to consider price, ingredients (plant-based vs. pharmaceutical), and user feedback on numbness and irritation. Different products work very differently for different people—you really have to try them yourself to know.
My Health Advice and Mental Adjustment
Beyond the product itself, I believe men's health is a systemic issue. Relying solely on a spray only treats the symptoms, not the root cause. While using the Kurohyo II, I've also tried to improve my condition from several angles:
1. Regular Exercise: I now jog 3-4 times a week, about 40 minutes each session. Exercise not only strengthens the body but also effectively relieves stress, which indirectly helps with sexual performance.
2. Adjusting Sleep Schedule: I try to get to bed before 11 PM and sleep 7-8 hours a night. Adequate sleep is crucial for the recovery of all bodily functions.
3. Healthy Diet: I eat more fruits and vegetables and cut down on greasy and high-sugar foods. Foods rich in zinc (like oysters and nuts) and B vitamins (like whole grains) are beneficial for male reproductive health.
4. Kegel Exercises: These exercises strengthen the pelvic floor muscles and help with ejaculatory control. I do a few sets daily—the short-term effects aren't obvious, but long-term consistency should pay off.
5. Mental Adjustment: Premature ejaculation is often linked to psychological stress and tension. I now try meditation or communicate more with my wife to lighten the mental load. After all, in a harmonious intimate relationship, communication matters more than anything.
Who Is This Kurohyo II For? Who Is It Not For?
Based on my experience, I think the Kurohyo II, this Japanese-imported male endurance delay spray for premature ejaculation, is suitable for:
* Those with mild to moderate premature ejaculation: If you only underperform occasionally or don't last long and want to boost your confidence, it's a solid choice.
* First-time users of delay products: Its price is relatively moderate, making it a low-cost entry point to test the waters.
* Those who prefer topical solutions: If you're comfortable with external products and don't want oral medication.
* Those who can accept some reduction in pleasure: If you're okay with a certain degree of reduced sensitivity in exchange for longer endurance.
But it may not be suitable for:
* Those with erectile dysfunction: The instructions also state that this product is mainly for delay and doesn't help with ED.
* Those who demand extremely high pleasure: If you can't tolerate any reduction in sensation, it might not be for you.
* Those who want instant results: Because it requires advance preparation, it's not ideal for "spur-of-the-moment" scenarios.
* Those with severe skin allergies or wounds on the genitals: Since it's topical, safety is paramount. It's best to test on a small area first or consult a doctor.
All in all, the Kurohyo II has been a fairly successful experiment for me. It solved my immediate problem and helped me regain some confidence. But I'm also aware that it's just a supporting tool—true men's health still relies on good lifestyle habits, a positive mindset, and proper exercise. I hope my real experiences and advice can serve as a useful reference for those of you who are still on the fence.
