Let me start with my situation. I'm 30 years old and work in sales, which is very stressful. Over the past two years, I've clearly noticed my duration has shortened—sometimes it's over in three to five minutes. My wife doesn't say anything, but I know she's not satisfied. I tried some oral products before, and while the effects were strong, the side effects were also obvious—facial flushing and heart palpitations. Later, I saw someone on a forum recommend topical delay sprays, saying they have fewer side effects, so I decided to give them a try.

After much deliberation, I finally bought Japanese Black Panther Duration Spray Third Generation Upgrade. My main reason was that it's made with a pure plant formula, and online reviews said it causes almost no numbness. Plus, the third-generation upgrade packaging looks more professional.

The first time I used it was on a Saturday night. After showering, I followed the instructions and sprayed once on the glans and coronal sulcus 30 minutes before intercourse, then spread it evenly with my finger. It felt a bit cool right after spraying, with no other discomfort. After waiting about 20 minutes, I touched it and noticed that sensitivity had indeed decreased, but it wasn't completely numb—I could still feel the touch, just not as intensely.

Once we started, the most noticeable change was that I could control the rhythm. Before, I'd lose control when nervous, but this time it lasted about 20 minutes. My wife was clearly more engaged than usual, and afterward, she asked why I was in such good form today. Based on my experience, the effect lasted about an hour before gradually returning to normal.

I used it two or three more times afterward, and here's a summary of the pros and cons:

Pros:
1. Almost no numbness: This was my main reason for choosing it. I tried a cheap one before, and after spraying, my glans was completely numb—sex felt like a chore. The Japanese Black Panther Third Generation does this well: sensitivity is reduced, but pleasure remains.
2. Sufficient duration: For someone with mild premature ejaculation like me, extending from three to five minutes to 20–30 minutes is more than enough.
3. Colorless and odorless: A few minutes after spraying, there's almost no smell, so it doesn't affect the mood.

Cons:
1. Needs 30 minutes in advance: Sometimes I only remember when things get heated, and I can't wait that long. I've since learned to spray in advance if I expect to be intimate.
2. Hard to gauge dosage: The first time, one spray was just right. The second time, I used two sprays, and it lasted too long, with reduced pleasure. I recommend beginners start with one spray and gradually increase.
3. May not be enough for severe premature ejaculation: A friend of mine with a more severe case tried it and said the effect was average—he might need something stronger.

For comparison, I've tried a few other products:

I also read an article about A Personal Test of Men's Delay Spray and MACA Erection Aid Experience, which mentioned that MACA erection aid mainly helps with erection, with average delay effects—similar to my experience. If the main issue is hardness, consider products with erection-boosting ingredients; if it's about duration, topical delay sprays are more direct.

Another article, German Import EROS Ilus 101 vs. Mainstream Delay Sprays: A Comparison Experience, also mentioned the Black Panther Third Generation, saying it's suitable for beginners—I agree.

As for the Japanese Black Panther Duration Spray 4th Generation, it's said to act faster than the third generation. I haven't tried it, but reviews suggest it has many improvements.

Finally, a few reminders: Start with a small dose the first time, wait 30 minutes after spraying, and increase the dose next time if needed. Avoid spraying on the urethral opening, as it can sting. If you have high blood pressure or heart disease, consult a doctor first.
