I am 42 years old and often see discussions about endurance issues in fitness communities. With frequent overtime at work and a fast-paced lifestyle, I recently noticed that my intimate moments felt a bit shorter, so I decided to try an external endurance spray.

After seeing the description of the German Black Diamond Endurance Spray - Male Premature Ejaculation Delay Spray, Non-Numbing, No Side Effects, Hong Kong Version, which claims a mild formula with no numbing sensation, I bought a 15ml bottle. The first time I used it was on a weekend evening. After showering, I sprayed twice evenly on the penis and glans, strictly waiting 8 minutes before starting. The effect gradually set in, extending the duration by about 25 minutes, and the whole process felt more natural than before.

The second time I used it on an empty stomach, it took effect faster—about 7 minutes—and lasted over 30 minutes. The third time, after dinner, I waited nearly 12 minutes for a noticeable effect, and the duration increased to about 28 minutes.

The principle behind this external endurance spray is mainly to locally and gently regulate blood flow and sensitivity, unlike some pills that require full-body absorption. The ingredients in the German Black Diamond Endurance Spray are said to contain antibacterial elements, with no dependency even with long-term use.

Another product I tried is the German Diamond Endurance Cream - Delay Spray, Male Enhancement, Adult Novelty Item, Best Seller, which takes 2-3 minutes longer to take effect than this one but has a similar duration. There's also the German Imported EROS Ilus 101 Male Endurance Liquid - Super Strong Delay, Authentic with Anti-Counterfeit Verification, which left a slight numbing sensation after spraying—something the German Black Diamond Endurance Spray completely lacks.

Usage is simple: spray up to 4 times, with 1-2 sprays recommended for first-time use, and store in a cool place. Precautions include never ingesting it and waiting long enough after spraying.

There are two drawbacks. First, the spray nozzle sometimes dispenses unevenly, making it easy to over-spray. After the first use, my glans felt a bit cool, which wasn't painful but required getting used to. Second, the price: one bottle lasts about 10 uses, making the per-use cost higher than regular delay sprays.

I also referred to Real Experience Sharing After One Month of Using Cologne Men's Endurance Spray - mp74i8120 and Personal Test of German EROS Ilus 101 Third-Generation Enhanced Endurance Liquid After Long-Term Use - mp5owt970, and their descriptions of the sensation matched mine.

Common questions include: how many sprays are best? I recommend starting with 1 spray and adjusting based on your reaction. Another is whether there are side effects. I've used it for three weeks without any issues, except once when I sprayed too much and it felt a bit dry.

In summary, the German Black Diamond Endurance Spray is suitable for men aged 30-50 with mild premature ejaculation issues who want a natural delay. It is not recommended for those with easily allergic skin or who have never used external products; it's best to start with a small test.
