Let me first describe my situation. I'm 42 years old and work in sales. Over the past two years, the pressure has been high, and my marital intimacy time has noticeably shortened—usually just three to five minutes. My wife doesn't say it out loud, but I know she's not fully satisfied. I've tried some oral medications before, and I've also heard of things like Wannai Spray, but I never dared to try them, fearing side effects. Later, a friend recommended a topical spray, saying it's safer, so I bought a bottle of Kulian Spray to give it a shot.

The first time I used it was on a Saturday night. After showering, I sprayed about one pump on the coronal sulcus of the glans, spread it evenly with my finger, and waited about 20 minutes before starting. For the first 10 minutes, I didn't feel much, and I was a bit worried. But after 20 minutes, there was a slight warm sensation—not numbness, but a noticeable reduction in sensitivity, though touch was still there. That session lasted about 40 minutes, more than three times longer than usual, and my wife was quite surprised.

I continued using it for two weeks, roughly twice a week. Here's what I observed:

The onset time is closely related to the dosage. I usually spray once, and it takes about 15-20 minutes to take effect; if I spray twice, the time shortens to around 10 minutes, but the duration extends to about an hour. However, with a larger dose, there's a bit of numbness, so I've stuck to just one spray since.

As for lasting power: on average, each session lasts about 45-60 minutes, which is more than enough. It also seems to help with hardness—erections feel firmer after spraying, though that might be partly psychological.

There are downsides too: First, the spray nozzle design isn't very user-friendly—it's hard to control the pressure when pressing, so you can easily spray too much. Second, you can't get it wet within 20 minutes after spraying; once I forgot and washed it off, and the effect was diminished. Also, the price isn't cheap—around 150 yuan per bottle, which lasts about a month if used twice a week.

For comparison, I've tried Yilusi 101 (a friend's). Yilusi works faster, about 5 minutes, but the numbness is more pronounced, and my wife didn't like the sensation. There's also an article I read analyzing Beinali Experience, which notes that Beinali lasts longer but is harder to dose. As for proper usage, you can refer to Wannai Usage Guide—that article covers common mistakes beginners often make.

Summary:
Suitable for: Those with shorter duration who want natural delay and dislike numbness; beginners using spray for the first time (start with one spray).
Not suitable for: Those allergic to alcohol (the ingredient contains ethanol); those seeking extreme endurance (e.g., over 60 minutes); those wanting instant effect (within 10 minutes).
