Let me start by sharing my situation. I'm 35 years old, working in the IT industry, sitting for long periods and under a lot of stress. Over the past two years, I've clearly noticed that my stamina has decreased. Although my wife doesn't say anything outright, I can sense she's not entirely satisfied. I've tried some oral products before, and they did work, but I always worried about side effects, so I later switched to topical delay sprays.

This time, I bought the Japanese Black Panther Duration Spray Third Generation Upgraded Version. I mainly chose it because it's a Japanese brand, and since the third generation is an upgraded version, I figured it should be better than the second generation. The packaging is 3D-style and looks quite premium. It's a 10ml bottle—not big, but enough to last a while.

Let me walk through my usage process in chronological order:

The first time I used it was about an hour after dinner. Following the instructions, I sprayed once on the glans and the coronal sulcus, gently massaged for about 60 seconds, and waited for it to absorb. Honestly, right after spraying, there was a cool sensation, but no stinging. After about 20-plus minutes, I felt a slight warmth in the area, but it wasn't numb. Then when my wife and I started, I clearly noticed my sensitivity was reduced. Before, I might have finished in a few minutes, but this time I lasted about 20-plus minutes, and my wife was pleasantly surprised. The whole process was comfortable, with no redness, swelling, or allergic reactions afterward.

I used it a few more times afterward. Here's my summary:

Onset time: The instructions say it takes effect in 30 minutes for temporary use and reaches optimal effect at 60 minutes. I tried spraying 30 minutes in advance, and the effect was indeed better—it felt more natural without sudden numbness. If you're in a hurry, you can start about 5 minutes after spraying, and it still works, but the effect is reduced.

Duration: Based on my experience, it lasts about 1 to 2 hours, depending on the dosage. One spray extends time by about 30-40 minutes, and two sprays can reach 50-60 minutes. Once I sprayed twice, and my wife was begging for mercy, haha.

Side effects: This is important to address. The first time I used it, there was some numbness on the glans, but it wasn't severe—just less sensitivity, though the sensation was still there. Also, if you spray too much, there's a slight burning feeling, especially if the skin has any breaks. Another time, I washed it off before it fully absorbed, and the effect was significantly reduced, so it's best to wait about 5 minutes before washing.

Now, let me compare it with the fourth generation, because I later tried that one too—the Japanese Black Panther Duration Spray Fourth Generation for Men. I did a simple comparison:

Overall, the fourth generation is indeed superior, but it's also pricier. If you're a beginner looking to try it out, the third generation offers better value; if your budget allows and you want a better experience, go straight for the fourth generation.

Additionally, I've tried other brands of delay sprays, like the German-imported EROS Yilusi 101, which a friend recommended, saying it doesn't cause numbness. I tried it, and it indeed had almost no numbness, but the delay effect was average—about 20-plus minutes—and it wasn't cheap either. I've also seen reviews of Jiuhuang and Black Diamond, but I haven't tried them myself.

Speaking of choosing a delay spray, besides the brand, you should also pay attention to the ingredients. Products like Black Panther with pure botanical formulas are relatively mild, but effects vary from person to person. The first time I used it, since I wasn't familiar with it, I sprayed twice, and it was too numb. After reducing to one spray, it was much better. So beginners should definitely start with a small dose and not overdo it.

Let me also discuss usage precautions:

1. It's best to clean the area before spraying and keep it dry for better absorption.
2. Don't spray too close—about 10 centimeters away is ideal, and 1-2 sprays are enough.
3. After spraying, gently massage and wait about 60 seconds for absorption.
4. If you plan on oral sex, spray 30 minutes in advance and then wash it off, so there's no taste.
5. Don't spray too much—a maximum of 4 sprays. More than that can cause numbness and affect sensation.

As for drawbacks, I see three points: First, the price isn't cheap, so if used frequently, the cost adds up. Second, effects vary by person—my friend said it delayed for a long time, but for me, it was only about 30-plus minutes. Third, if you don't wash it off after spraying, there's a faint herbal smell. It's not strong, but if you're sensitive to it, I'd recommend spraying in advance and then washing.

In conclusion, the Japanese Black Panther Duration Spray Third Generation Upgraded Version is suitable for those trying topical delay sprays for the first time. It offers stable effects and a moderate price, but it takes a bit of time to get used to. If you want a more natural and longer-lasting experience, you could look at the fourth generation or the German EROS. But no matter which one you choose, remember: start with a small dose the first time, don't be greedy, and safety comes first.

If you're still torn about which to choose, you can refer to my earlier article on selecting delay sprays, which includes more detailed comparisons.
