I am 42 years old and work as an engineer at a tech company. In the past two years, I've been working overtime a lot with high stress, and I noticed that my intimate time was a bit short, so I decided to try an external endurance spray. Seeing that the German Black Diamond Endurance Spray claims to be numbing-free with no side effects, I bought a Hong Kong version online.

The first time I used it was on a Friday night, about an hour before bed. I followed the instructions and sprayed twice on the glans, waited about 8 minutes, and started to feel a slight warmth but no numbness. During the act, the time increased by about 25 minutes compared to usual, lasting around 30 minutes in total, and it felt much more natural.

The second time, a week later, I tried spraying three times to see the difference in effect. It still took about 8 minutes to kick in, and the duration extended to about 35 minutes. However, this time I felt a bit of a cooling sensation, probably because I used a little more. For the third and fourth times, I controlled it to two sprays, and the sensation was more stable, with the delay effect maintaining over 30 minutes.

Regarding the types of external endurance products, they are generally divided into sprays, ointments, and gels. The principle is mainly to reduce sensitivity through mild ingredients to prolong time. The German Black Diamond Endurance Spray falls under the spray category, with a formula emphasizing sterilization and endurance, and it is said to have no dependency with long-term use.

In terms of ingredients, these products often contain local anesthetics or plant extracts, but the German Black Diamond emphasizes no numbness, so I guess it uses a milder formula. When using, it should be sprayed on the shaft and glans, not for internal use, and it has a shelf life of two years.

I also read Louis 16 Endurance Spray Used Three Times - My Real Endurance Experience-mppon5vw0 and Used Indian God Oil Spray for Three Weeks - Recording My Real Endurance Changes-mpo9oiyq1, and their experiences felt different from mine.

Compared to other products, I tried the German imported EROS 101 Male Endurance Liquid, which has super strong delay and is genuine with anti-counterfeit verification. It takes effect slower, about 15 minutes, but lasts longer. The German Diamond Endurance Ointment Spray for male enhancement and adult fun products is a paste, making it harder to control even application.

Simple comparison:

There are two drawbacks. First, the spray amount needs to be very careful; the first time I sprayed too much and felt a bit uncomfortable. Second, the bottle design makes it easy to dispense too much, making control inconvenient. Also, you need to wait for it to dry after use, otherwise it affects the sensation.

I think the German Black Diamond Endurance Spray is suitable for people around 40 who want to try external endurance sprays but are afraid of numbness. It is not suitable for those with sensitive skin or those on medication; it's best to consult a doctor first.
