I am 38 years old, working in the IT industry with a lot of overtime and irregular sleep patterns. In the past two years, I've noticeably felt that my intimate time has shortened. A friend mentioned topical endurance products, so I first looked up some information online and decided to try Japan Beilitin Men's Endurance Gel 2H2D Delay Liquid, Adult Product Male Delay Spray. This is a topical endurance liquid, and its principle is roughly to reduce sensitivity through local ingredients to prolong duration.

The first time I used it was on a weekend evening. After showering, I applied a thin layer to the key area, about the size of a grain of rice. I waited about 25 minutes before feeling the effect. The process felt natural, without sudden numbness. The entire session lasted about 1 hour and 40 minutes longer than usual, and I didn't experience any particular discomfort afterward.

The second time I used it was a week later. I tried using it on an empty stomach, and it took effect faster—about 20 minutes for a reaction—lasting a bit over 2 hours. However, this time I applied a bit more, and afterward, I felt a noticeable reduction in sensitivity, which took about half an hour to return to normal.

For the third time, I learned my lesson. I applied it 10 minutes in advance, controlling the amount to half of the first time. It took effect in about 30 minutes, lasting nearly 2 hours, with a better overall balance. During the process, I noticed that whether I had eaten or not didn't make much difference, but pre-application cleanliness was important; otherwise, it could feel sticky.

I had also looked into other types before, such as the oral 2H2D Black Maca 120 Capsules, Delay and Hardness Enhancement Maca Tablets, which work through systemic regulation, taking effect slowly but potentially lasting longer. In comparison, topical endurance liquids work faster but have a smaller scope of action. I also checked out the Japan 2H2D Black Gold Edition Endurance Liquid Spray, Anti-Premature Ejaculation Delay and Erection Aid, Recommended by Watsons, with Free Platinum Travel Set. The spray version is easier to apply evenly than the gel, but it has a slightly stronger odor.

Comparing other products, I've briefly listed the following:

As for drawbacks, first, it requires advance preparation and cannot be used on the spot. The second time, I almost delayed because I didn't leave enough time. Second, the reduced sensitivity can diminish pleasure; once after use, I felt a bit "numb," though not painful, the experience wasn't as intense. Third, the bottle design makes it hard to control the amount dispensed, easily leading to overuse.

My own summary of usage precautions: Don't use if there are skin injuries or a history of allergies; test on a small area first. Don't use simultaneously with condoms unless compatibility is confirmed. If using continuously for more than a week, it's best to take a few days off to observe.

Previously, I saw Black Diamond Endurance Liquid Used Several Times Delay Comparison Record-mpzout0l0 and Real Record of Using Japan Maru Ei 2H2D Platinum Endurance Spray Three Times-mpy9l3000, which mentioned similar onset curves, and my experience felt about the same.

Overall, the Japan Beilitin Men's Endurance Gel 2H2D Delay Liquid is suitable for men who want to try topical endurance liquids for the first time and hope to see quick results, especially those concerned about oral health supplements. It is not suitable for those with sensitive skin, who seek an extremely natural feel, or who have a limited budget for long-term use.
