Let me first give some background: I'm 35 years old and work in sales. These past two years, I've had a lot of social engagements and a messy schedule, and I can clearly feel that my stamina is not what it used to be. Sometimes at night when it's time to "hand in my homework," I always feel like I'm not up to it and finish hastily, which makes things a bit disappointing for both of us. For this issue, I've spent no small amount of time reading guides online and tried all kinds of methods.

This time I chose German King Kong mainly because online reviews said it does not numb and also helps with premature ejaculation and delayed erection. At the time, I bought a 10ml bottle of topical endurance liquid, thinking I had to give it a try—at least it was some hope.

The first time I used it was on a weekend night, and I took a shower in advance. According to the instructions, I sprayed German Black King Kong evenly on the shaft and glans. To be honest, I was quite uncertain at the time, afraid that, like some cheap products I had used before, it would make the whole thing lose sensation, and then there would be no way to enjoy it at all. As it turned out, after spraying, I waited about 8 minutes and felt a slight warmth in the area, but definitely not that rigid numbness. That night, the whole process lasted about 30 minutes longer than usual. It was a long-awaited relief, and both of us were very satisfied.

Later, I used it several more times and figured out some patterns and details:

About onset time and sensation: as long as the skin absorbs it well, you can basically be fully in the zone within 8 to 10 minutes. It is not the kind of erection aid that makes you hard as iron; it is more like a physical-level endurance aid that lowers your sensitivity to just the right range, so you can maintain hardness while also controlling the rhythm well.

However, in actual use, I also found a few rather troublesome shortcomings, or should I say inconvenient aspects:
1. The nozzle design makes precise control a bit difficult. Sometimes with a slip of the hand, I sprayed too much. The instructions say to spray at most 4 times, but the first time I accidentally sprayed 5 times, and that night I felt a little overheated. In the latter half, I almost couldn't hold back, and it ended up lasting so long that it was actually a bit tiring.
2. In terms of smell. Right after spraying, you can smell a faint medicinal liquid odor. Although it dissipates quite quickly (about two or three minutes), if your partner minds this smell, it might feel like a bit of a mood killer.

To understand it better for myself, I also compared it with two other products I had on hand. The general situation is as follows:

Onset speed comparison:

* Imported German Black King Kong: about 8 minutes, fast and natural.
* Competitor one (refer to eros101 endurance liquid): needs to wait about 15 minutes, slightly slower to take effect, but the subsequent stability is good.

Duration comparison:

* Imported German Black King Kong: can reliably extend by more than 30 minutes, with good explosive power.
* Competitor two: can only extend by about 15 to 20 minutes, and the staying power is somewhat insufficient.

Side effects and numbness comparison:

* Imported German Black King Kong: basically no numbness, only a slight heating sensation.
* Some inferior products: after use, it feels like anesthesia, completely no sensation, and the experience is extremely poor.

If you have a need for this kind of product, you can take a look at some reference articles I wrote before, such as this record about the eros101 experience, or see the Marunai pit-avoidance guide on how beginners can avoid pitfalls. The purchasing logic mentioned in them is actually much the same.

Finally, let me talk about my personal advice and see who it is suitable for and who it is not suitable for:

This thing is very suitable for adult men whose overall physical foundation is still okay but who have short durations each time because of high pressure or excessive sensitivity, especially those who pursue a realistic sensation and dislike that rigid numbness. But if you are a patient with severe cardiovascular disease, or someone allergic to alcohol and topical herbal ingredients, do not blindly follow the trend and try it. In addition, first-time users must restrain themselves. Spray 1-2 times first to test the waters, and do not do what I did at the beginning and almost overdose.
