1. Why I Bought This Bottle of Wannai Zhanhun

Let me first explain my situation: I'm 40 years old, married, have a child, and work an ordinary job. My work pace is relatively fast, and I often stay up until after 11 PM before sleeping. Over the past two years, I've clearly felt my condition isn't what it used to be. The most direct issue is that my duration has shortened, from over ten minutes before, gradually dropping to around 5 minutes. Sometimes, when stress is high, it gets even faster.

Initially, I didn't plan to use medication. I first tried adjusting my routine, drinking less alcohol, and sticking to brisk walking and squats. After persisting for about two months, I felt a slight improvement, but it only went from 3-5 minutes to 5-7 minutes. My wife's expression was still a bit hard to read.

Later, while chatting in a group, someone asked, "Do external endurance sprays actually work?" I was curious myself, so I decided to take notes and act as a guinea pig. After comparing a range of external endurance sprays, I ended up buying:

Wannai Zhanhun Men's Endurance Spray 10ml Delay Spray Endurance Liquid Bestseller Must-Have (main test subject)

I had used a bottle of German spray before, and this time I conveniently bought the Hong Kong version of the German solution: for example, sprays with a similar approach to German Black Diamond

Additionally, I got a German-made product for comparison, with a style roughly similar to EROS Endurance Liquid

The following experience is basically a record of the past three weeks, with a fairly detailed timeline, to serve as a reference for anyone considering trying external endurance sprays.

By the way, if you have absolutely no experience with this kind of thing, you can first check out an older article on the site, Choosing External Endurance Sprays. The overall logic is quite clear, and it was after reading that article that I started systematically recording my usage experience.

2. First, Let's Talk About What External Endurance Sprays Actually Do

In my own understanding, external endurance sprays mainly do two things:

1. Reduce the sensitivity of the glans, delaying the ejaculation reflex
2. Through some herbal or cosmetic-grade ingredients, improve local blood flow, providing a sensation of "warmth" and "engorgement"

Compared to oral medications:

External: Acts locally, works quickly, highly controllable, no lasting effect after stopping, theoretically less burden on the body

Oral: For example, Japanese Taiso, American Black Gold, Blue Pills, etc., affect erection and endurance through systemic circulation. They might be more potent but place higher demands on the cardiovascular system, liver, and kidneys.

I chose the external route for two reasons:

My erections were fine; the issue wasn't getting hard, but finishing too quickly

I didn't want to start with pills right away, as it felt psychologically stressful

So, the main focus this time was on various sprays and external endurance liquids.

3. First Use of Wannai Zhanhun: From Hesitation to Application

I bought the officially labeled 10ml Wannai Zhanhun version, with a reference price of around a little over one hundred yuan. Depending on promotions, it can sometimes be close to just over one hundred.

First use time:

Showered at 9:30 PM

Sprayed around 9:40 PM

Started around 10:00 PM

Usage steps (according to my own process):

1. Washed the genital area thoroughly during the shower, focusing on the glans and coronal sulcus, for about 1 minute
2. Dried off and waited about 5 minutes to ensure complete dryness
3. Held the nozzle about 5 cm away, pressed twice, mainly spraying the glans and coronal sulcus, without deliberately spraying the entire shaft
4. Gently spread it evenly with my hand, for about 10 seconds
5. Let it sit and absorb, waiting about 20 minutes

This time, I didn't rinse it off, fearing I would wash away too many active ingredients.

First-time sensation and duration:

1-2 minutes after spraying: A bit cool, then a slight warmth, not a burning sensation. I could clearly feel something on the skin.

Around 15 minutes: The warmth stabilized, no stinging, just a slight presence.

After starting:

- Originally, it was under 5 minutes. This time, I checked my phone, and from start to finish, it lasted about 15 minutes, much longer than usual.
- During the more intense moments in the middle, I could clearly feel that my sensitivity was suppressed. It wasn't "numb," but the pleasure was slightly dulled.

My wife's feedback: She said, "This time felt just right, not like before when it ended so quickly." She also didn't mention any issues with odor.

Summary of the first use:

Onset time: About 20 minutes to stabilize

Duration: For that night, the actual time was about 2-3 times longer than usual

Discomfort: It felt a bit sticky after spraying, and there was some friction against my pants, not major, but noticeable.

4. Feelings After Three Consecutive Uses: Dosage and Onset Time

Over the next week, I used it three more times, roughly every 1-2 days, for easier comparison:

#### Second Use (About 3 Days Later)

Time: Sprayed before 10 PM, started around 10:20 PM

Dosage: Still 2 sprays

This time, I played on my phone in bed after spraying. After about 10 minutes, I clearly felt the "warmth" was slightly weaker than the first time, probably due to psychological expectation.

Actual duration: From start to finish, about 18 minutes (I checked the time this time)

Feeling:

- For the first 10 minutes, there was almost no sense of urgency to ejaculate.
- After 15 minutes, my physical stamina started to give out first, and my breathing became a bit rapid.

One small issue this time: I put on my underwear too soon after spraying and walked around, causing a small ring of liquid near the glans to rub onto other parts of the penis. This led to a slight extension of the warmth later. Overall, it wasn't a big problem, but it felt a bit uneven.

#### Third Use (Another 2 Days Later)

Time: Close to midnight, in a relaxed state of mind

This time, I tried spraying only once to see how a lower dose would work.

Waited about 15 minutes

Onset sensation: Almost no noticeable warmth, just a tiny bit of coolness

Actual duration:

- This time, it was around 12 minutes, slightly longer than without any spray, but not as noticeable as with 2 sprays.

My conclusion that night was: For me, 1 spray is too conservative, 2 sprays are suitable, and I haven't dared to try 3 yet.

#### Fourth Use (About a Week Later)

This time, I deliberately did a "small experiment": half the time with a condom, half without.

Dosage: 2 sprays

Onset time: Still about 20 minutes

First half without a condom:

- The pleasure was slightly reduced, but not like the "complete numbness" of traditional numbing sprays. It was within a natural range.
- After about 10 minutes, I felt a clear urge, but I could control it.

After switching to a condom:

- Sensitivity dropped further. For the last few minutes, it was mainly my physical stamina that was the limiting factor.

That time, I roughly calculated that the total duration was over 20 minutes, without any breaks.

5. Comparison with Two German Sprays: Onset, Duration, Side Effects, Price

This is the most frequently asked question. I'll compare Wannai Zhanhun with two German-style sprays (without brand worship, let's call them "German 1" and "German 2") across several dimensions:

#### 1. Onset Time

Wannai Zhanhun:

- For me, it stabilizes in about 20-25 minutes. There's a slight coolness and warmth in the first 5 minutes after spraying.

German 1 (similar to German Black Diamond):

- Onset is relatively fast, about 10-15 minutes to feel a clear "local desensitization," somewhat like a mild numbness.

German 2 (similar to EROS Endurance Liquid):

- Onset is slower, about 25-30 minutes. The advantage is that the sensation is milder.

Subjective feeling: If you're spontaneous and often "go for it on a whim," German 1's faster onset is better. If you're used to some foreplay time, Wannai Zhanhun's 20-minute onset is also acceptable.

#### 2. Endurance Effect (Based on My Own Sensation)

Using my baseline of about 5 minutes without anything:

Wannai Zhanhun:

- 1 spray: About 10-12 minutes
- 2 sprays: Commonly in the 15-20 minute range

German 1:

- With moderate dosage, about 20-25 minutes, but pleasure is more noticeably suppressed.

German 2:

- Duration fluctuates between 10-18 minutes, with the advantage of feeling natural, without strong local sensations.

Summary:

For "as long as possible": German 1 is slightly better.

For "endurance + preserving pleasure": Wannai Zhanhun and German 2 suit me better.

#### 3. Adverse Reactions & Inconveniences

Here are a few complaints from my weeks of use, especially regarding Wannai Zhanhun:

1. Nozzle and dosage are not precise enough
- The nozzle of Wannai Zhanhun releases a bit too much liquid per spray for my liking, making it hard to achieve precise "half-spray" control.
- Once, I sprayed too close in a hurry, resulting in a thick patch of liquid locally, which led to a stronger warmth later.

2. Some residual feeling
- If not washed off, after spraying and putting on underwear, walking around makes the glans feel slightly sticky.
- Post-activity cleaning requires a bit more effort; otherwise, there's a slippery layer.

3. Disadvantages of German 1:
- Local numbness. Must be thoroughly washed off before oral sex, or both parties will be uncomfortable.
- Once, I didn't rinse thoroughly enough, and my wife's lips felt slightly numb, earning me a scolding.

4. Disadvantages of German 2:
- Onset is too slow, not suitable for "sudden bursts of interest."

So, Wannai Zhanhun strikes a balance between "non-numbness and endurance effect," but the nozzle control and slight stickiness are aspects I dislike.

#### 4. Price and Cost-Effectiveness

Based on the approximate price range I bought at (reference for early 2026):

Wannai Zhanhun (10ml): About 1XX yuan. With 1-2 sprays per use, it can last for 20-30 uses without issue.

German 1 (10ml): Generally slightly more expensive, but with stronger endurance.

German 2 (10ml): Price is similar to Wannai Zhanhun, sometimes cheaper during promotions.

From a cost-effectiveness perspective:

Focus on "maximum endurance limit": Lean towards German 1.

Want "non-numb + moderate-to-high endurance + reasonable price": Both Wannai Zhanhun and German 2 are worth considering.

Pure budget-conscious: Check promotional prices, try whichever is cheaper first; the difference isn't huge.

By the way, if you just want to understand the pitfalls of external endurance sprays, you can check an old review, like Pitfalls of Using Jiuhuang, which details the issues of "dosage" and "whether to wash." It was after reading it that I started paying attention to dosage control.

6. Overall Performance of Wannai Zhanhun Over Three Weeks: Pros and Cons

#### 1. What I Approve Of

1. Stable endurance effect
- Used about 7 times over three weeks. Except for one time with only 1 spray, which was weaker, the rest consistently lasted around 15 minutes, 2-3 times longer than without use.

2. No significant systemic side effects
- No headaches, palpitations, or other systemic reactions, which is why I chose external over oral.

3. Not "completely numb"
- Compared to some numbing sprays, Wannai Zhanhun's impact on pleasure is moderate. I can still clearly feel friction and excitement, just that the "point of no return" is delayed.

4. Works well with condoms
- Maintains some sensitivity during the condom-free period, and switching to a condom later adds a few more minutes. It's friendly for those wanting to balance safety and experience.

#### 2. What I'm Not Satisfied With (Key Points)

1. Nozzle is not precise enough
- It's hard to achieve the "thin layer" as described in the instructions. In practice, it's either too concentrated and excessive, or the spray range is not focused.
- I later resorted to spraying it on my hand first and then applying with my fingers, which is slightly better but adds an extra step.

2. Residue and cleaning issues
- If not rinsed before intimacy, I always have a psychological worry: "Will it make her lips numb?" Although this hasn't happened yet.
- Post-activity cleaning requires some body wash; otherwise, the slippery feeling is hard to completely remove, which is a bit troublesome.

3. Onset is a bit slow, not ideal for spontaneity
- It requires spraying 20 minutes in advance, meaning you need to plan intimacy. For families with children, the "window of opportunity" is often short, and sometimes the child wakes up before the spray takes effect.

4. Psychological dependence
- This is my own state: After using it a few times, I worry that without it, I'll go back to 5 minutes, even though I rationally know it's just a tool.

7. How to Use It More Reasonably: Dosage, Timing, and Habits

Based on my three weeks of experience, here are some suggestions for those planning to try Wannai Zhanhun (or similar Wannai Zhanhun version):

1. Start with a low dose
- For the first time, I recommend spraying only once to check for any local allergies, stinging, or other abnormalities.
- If there are no issues, try 2 sprays next time. Don't go overboard from the start.

2. Control the timing
- A safer approach: Shower 30 minutes before intimacy → Dry off and wait 5 minutes → Spray → Wait another 20 minutes.
- This ensures absorption and allows excess liquid to dry slightly, reducing stickiness.

3. Should you wash it off?
- If oral sex is planned, it's advisable to rinse the surface with water after onset, avoiding hot water.
- If only using a condom for penetration, you can skip washing, but be careful not to transfer too much to your partner's genital area.

4. Don't expect it to solve everything
- External endurance sprays only help you "buy time." If your daily habits are poor—staying up late, smoking, lack of exercise—your overall condition will continue to deteriorate.
- You can also combine it with:
- 30 minutes of brisk walking daily
- 2-3 times a week of squats or deadlifts for leg training
- Not scrolling on your phone too late before bed

5. Communicate with your partner
- I initially used it secretly, but my wife found out. Her attitude was, "You're making an effort on this, that's good." It actually made us both more relaxed.
- If your relationship is good, it's better to be upfront; the effect is often better.

If you're nervous about how to start the conversation, you can look up content on couple communication. The general idea is to emphasize "sharing feelings, not blaming," which is the right direction.

8. Who It's Suitable For and Who It's Not

Finally, let me be direct about who I think these external endurance sprays, especially the Wannai Zhanhun type, are suitable for:

Men aged 25-45, with basically normal erectile function, just short duration

No clear organic issues found in medical exams, leaning more towards "psychological tension + high sensitivity"

Don't want to start with oral medication right away, preferring to try external options first

Accept the "prepare 20 minutes in advance" pace and can cooperate with showering and waiting steps

Budget around one to two hundred yuan, wanting to try a bottle first

Not suitable for:

Those with significant erectile dysfunction, often experiencing mid-way softening

Those with severe cardiovascular disease or taking many medications; such individuals should consult a formal medical facility first

Those who absolutely cannot tolerate any sensation of warmth or foreign body

Those who think "one bottle will cure it from the root" and treat it as a miracle drug

Additionally, if you're already using oral products like Japanese Taiso, American Black Gold, or Blue Pills, layering external sprays on top can make control extremely strong, potentially leading to "inability to ejaculate for too long." It's not recommended to start with both at once. Try one type alone first and see how you react.

For myself, my current plan is:

Keep external sprays as a backup, for occasional poor performance or special occasions

Rely on improving sleep + exercise + stress reduction in daily life

After three weeks of testing, my subjective evaluation of Wannai Zhanhun is: Medium-to-high cost-effectiveness, stable effect, some minor flaws, but not a dealbreaker. If you're like me, with a decent baseline and just want to last an extra ten-plus minutes, this type of external endurance spray can be an option in your toolbox, but don't pin all your hopes on it.
