First, let me give you some background. I'm 40 years old and work in operations. Over the past few years, with lots of late nights and high stress, I've noticed my endurance getting shorter and shorter—sometimes just three to five minutes. My wife doesn't say anything, but I know she's not fully satisfied. I tried some health supplements before, but the results weren't great. Later, I saw many people on forums recommending topical sprays, so I got interested.

After some research, I went with this product: German King Kong Endurance Cream Delay Spray for Male Enhancement, Adult Fun Items, Must-Have Bestseller. I chose it because, first, it's a German brand, which seemed more reliable, and second, the price was reasonable—just a few dozen yuan per bottle, so even if it didn't work, I wouldn't feel bad about the cost.

The first time I used it was on a weekend night. After showering, I followed the instructions and sprayed twice on the glans and corona, then gently massaged for a while. It felt cool, and after about ten minutes, my skin started to feel slightly warm, but not numb. Around 20 minutes later, we started, and I definitely felt more in control—not as eager to finish as before. That session lasted about 25 minutes, more than double my usual time, and my wife was pleasantly surprised.

I used it a few more times after that, and here's a summary of my experience:

Now, for the downsides:
First, if you don't wash your hands after spraying, your fingers might feel a bit numb, so remember to wash them immediately.
Second, it has a slight herbal smell—not unpleasant, but my wife could notice it, which was a bit awkward.

Later, I tried a few other products. Here's a quick comparison:

Regarding the principle behind these endurance products, I've read some articles before, like Is German Black King Kong Endurance Liquid's 8-Minute Onset Real? Pharmacist Explains the Delay Mechanism - mqmjrne40, which explains it clearly. Basically, they use local anesthetic ingredients to reduce sensitivity, but different brands' formulas and concentrations affect the degree of numbness.

I also tried a gel-type product. You can check out Using Japanese Beiliting Gel for a Month: Real Feelings on Endurance - mqjowuic1. That gel had a slower onset but was gentler, suitable for those who don't like sprays.

In summary, the German King Kong Endurance Cream is a good choice for first-time users of topical endurance products. It offers decent value and stable results, but if you're sensitive to numbness, consider EROS Yilusi. It's not suitable for those who are very sensitive to numbness or prefer completely odorless products. Also, always follow the dosage instructions—don't overdo it.
