Let me start with my situation. I'm 38 years old and work as a project manager at an internet company. Working overtime is a daily routine for me. In the past two years, after the birth of my second child and as I've gotten older, I've clearly noticed that I'm not as capable as I used to be in the bedroom. Before, I could easily last 10 to 20 minutes, but now, when I'm a bit tired, sometimes I finish in just five or six minutes. My wife doesn't say anything, but the atmosphere always feels a bit awkward. One night, unable to sleep, I was browsing online and saw many people discussing delay products. I got curious and secretly ordered a bottle of a product with the full name "Japan Maruna Lasting Spray 15ml Men's Delay Classic Edition, Long-lasting Must-have, Topical Lasting Liquid." Why did I choose it? Mainly because it claims to be plant-based, non-numbing, and costs less than 1,000 NT dollars, so even if it turned out to be a dud, I wouldn't feel too bad about it.

When the package arrived, the packaging was very discreet, which was a plus. After opening it, there was a small 15ml bottle, about the size of a lipstick, easy to hide in a drawer or a travel bag without being too noticeable. The spray nozzle looked pretty ordinary. I gave it a sniff, and it had a faint herbal scent, not pungent, without that cheap perfume smell trying to mask chemicals. The first impression was decent; at least it didn't feel like some no-name chemical product.

The first time I used it was on a Friday night. After the kids fell asleep, around 10:30 PM, I followed the instructions and sprayed once on each side of the coronal sulcus and glans. It felt cool right after spraying. I thought it would take effect immediately like people online said, but after waiting about 10 minutes, I didn't feel anything special. I wondered if I had sprayed too little, but to be safe, I didn't add more. After about 20 minutes, I felt a slight warmth in the area. At the 30-minute mark, we got started. To be honest, this first experience was just passable. Since I wasn't sure of its limits, I was still a bit nervous, and I ended up lasting about 10 minutes, a few minutes longer than usual, but not the "super long-lasting" effect I had imagined. Fortunately, there was no numbness, and the sensation was still very real.

With the first experience under my belt, I decided to adjust my strategy. Four days later, around Tuesday after dinner, I saw it was about 9 PM, so I went to the bathroom early to shower and sprayed twice. This time, I was smarter: after spraying, I gently spread it with my finger to help absorption. About 25 minutes after applying, the warming sensation was more noticeable than last time. This time, I deliberately waited nearly 40 minutes before starting. The effect was much more obvious! Including foreplay and the main event, I lasted nearly 20 minutes. A few times when I felt close to finishing, I slowed down a bit, and the urgency quickly subsided. This was a big breakthrough for me. My wife even joked afterward, asking why I was in such good form today.

However, this product isn't perfect. I had a mishap later. One weekend, feeling relaxed, I wanted to test my limits and sprayed four times in one go. That was a disaster. About 15 minutes after spraying, the slight warmth turned into a distinct burning sensation, even a bit painful. I gritted my teeth and waited half an hour, but the discomfort didn't fade, so I had to go to the bathroom and wash it off with soap. This was the first major flaw I discovered: the dosage is extremely hard to control. Too little and it's ineffective; too much and it causes a burning sensation. The margin for error is quite low.

The second flaw is the long waiting time, which can kill the mood. It needs at least 30 to 40 minutes before use to achieve optimal results. This means you can't be spontaneous; you have to plan ahead like a project. Sometimes, when the mood strikes, and you suddenly say, "Wait, I need to spray something and come back in half an hour," the moment is instantly gone.

Later, for comparison, I did some research and borrowed a friend's experience to compare a few competing products on the market. Here's a quick table for reference:

| Product Name | Onset Time | Delay Effect | Sensation/Side Effects | Price Range |
| :--- | :--- | :--- | :--- | :--- |
| Japan Maruna | About 30-40 minutes | +10~15 minutes | Slight warmth, burning with overdose | Budget-friendly entry |
| 2H2D Black Gold Edition | About 20-30 minutes | +15~20 minutes | Gentle, almost no foreign body sensation | Mid-to-high price |
| German Black Diamond | About 15-20 minutes | +20 minutes or more | Slight numbness, fast onset | Mid-range price |
| EROS 101 | About 15-20 minutes | +15~25 minutes | Silicone base, high durability | Higher price |

Speaking of gentleness, if you have a sufficient budget, you might consider other high-end topical lasting liquids on the market, like Japan 2H2D Black Gold Edition Lasting Spray, Anti-premature Ejaculation Delay, Recommended by Watsons, Free Travel Size. My friend says this one absorbs faster, with effects felt in about 20 minutes, and almost no burning issues.

For those who want fast onset and can tolerate a slight numbness, European or American topical lasting liquids might be more suitable, such as German Black Diamond Lasting Liquid, Men's Anti-premature Ejaculation Delay Spray, Non-numbing No Side Effects, Hong Kong Version. It's said to be more direct in suppressing sensitivity, ideal for those who are naturally very sensitive.

There's also a high-end long-lasting option like German Imported EROS Ilus 101 Men's Lasting Liquid, Super Strong Delay, Authentic Anti-counterfeit Checkable. Due to its different formula, it offers more stable durability, but the downside is its price, which is a bit off-putting for regular folks like me.

Sometimes, the logic behind choosing these products is important. I once read an analysis article that explained it thoroughly. If interested, you can search for this article: Is Japan Maruna Men's Topical Spray Worth Buying? Unveiling the Sensation Logic Behind AV Actor Recommended Intimacy Products-mo9fqjec5. It includes many real reviews on sensation feedback.

Also, when buying such products, be sure to check for authenticity. There are too many fakes on the market, especially those claiming to delay for half an hour. I recommend doing some homework before purchasing. Check out this article: Key Points to Consider Before Buying Pirelli Delay Spray Authentic Lasting Liquid, The Truth About 40-Minute Delay Anti-counterfeit Query and Men's Special Use-mo9fpmu23. The anti-counterfeit methods mentioned are very practical.

During these weeks of experimenting with this spray, I gradually realized a problem: relying solely on topical products only treats the symptoms, not the root cause. The principle of topical lasting liquids is essentially to reduce local sensitivity through ingredients or slightly alter the threshold of nerve transmission. But for those of us in our mid-thirties, declining performance is often due to multiple factors.

I noticed that on days when I went for a run or did squats, my evening performance was significantly better, even without the spray, lasting about 10 minutes. According to my research, squats and Kegel exercises (PC muscle training) can effectively promote blood circulation in the pelvic area. Now, before my evening shower, I do about 3 sets of squats, 15 reps each. After sticking with this for about a month, the most noticeable change is stronger core strength. Before, I'd feel back pain after sex, but now I recover much faster. If you're serious about improving the root cause, spend 10 minutes a day practicing PC muscle exercises—contract for 3 to 5 seconds, then relax, repeating several dozen times. Over time, this greatly helps the muscle group controlling ejaculation.

Managing psychological stress is something I think many middle-aged men can relate to. Often, we reply to the last message in a work group or just calm down noisy kids, then have to switch to "romantic mode." How is that possible? The brain is still in a high-pressure, anxious state, with the sympathetic nervous system tense. In this state, it's easiest to "finish early." My later approach was to set aside about 20 minutes of quiet time before bed, without looking at my phone, chatting casually with my wife, or listening to some light music. When the mind relaxes, the sensitivity caused by tension decreases significantly. This 30-minute waiting period is actually a double-edged sword. If you can turn these 30 minutes into part of foreplay, like giving your wife a massage, knowing you've "got insurance," the anxiety about poor performance lessens a lot. This boost in confidence is sometimes more effective than the physical delay effect of the drug itself.

A while ago, to meet a big project deadline, I stayed up late for nearly two weeks, sleeping only about 5 hours a day. During that time, even with the spray, I felt drained. Although the duration extended a bit, my hardness was completely off, and the experience was terrible. After the project ended, I caught up on sleep, ensuring 7 hours a night, and started taking zinc supplements and maca. About two weeks later, the frequency of morning erections noticeably returned. Basic vitamins and minerals are key. I supplement with about 1000 IU of vitamin D and B-complex daily. B-complex is crucial for IT workers like me who stare at screens all day and are prone to nerve fatigue—it helps stabilize the nervous system. When nerves aren't so tense and hypersensitive, control naturally improves.

Here are some practical tips I've figured out for those looking to try this:
First, rinse after spraying. Even though it claims to be plant-based, there's residue. If you plan on oral sex, it's strongly recommended to rinse with water after waiting 30 minutes for absorption. From my tests, rinsing doesn't affect the delay effect but prevents the ingredients from transferring to your partner and causing discomfort.
Second, avoid the urethral opening. When spraying, gently pinch the urethral opening and spray only around the coronal sulcus. If you accidentally get it inside, the sharp, stinging pain will make you never want to do it again.
Third, use it with lubricant. After using a delay spray, the duration increases, and sometimes the partner's natural lubrication decreases, increasing friction and causing discomfort for both. Using a water-based lubricant can significantly improve the experience.

Let me summarize my honest opinion on this product.

It's suitable for middle-aged men like me, in their thirties, who usually last 5-10 minutes and want to slightly improve quality by extending it by about ten minutes; or for those who particularly dislike the numbness of "feeling like a piece of wood" and seek a real sensation; or for first-timers with a low budget who want to try an affordable option.

It's not suitable for those with severe premature ejaculation who can only last 1-2 minutes—this can't be fixed with a budget topical spray; seeing a doctor is more reliable. It's also not for those who aim for half-hour marathons in bed—based on my experience, this product's limit is about adding 15 minutes max. If your sex life is spontaneous and you like to go at any time, this product requires half an hour of preparation, making it completely unsuitable for surprise attacks.

Now, I basically use this Maruna spray as an occasional auxiliary tool. I rely on adjusting my routine and exercise to maintain my baseline. On weekends, if I want to add some spice or when I'm particularly tired but don't want to disappoint, I'll spray twice. A man's pride is important, but physical foundation is the real capital.
