Let me start by sharing my situation. I'm 35 years old, working in sales, usually under a lot of pressure, and my daily routine is irregular. Over the past year or so, I've clearly noticed that my performance in that area isn't what it used to be—sometimes I'm done in two or three minutes. My wife doesn't say anything out loud, but I can feel she's a bit disappointed. I've tried some health supplements before, but the results were mediocre. Later, I saw someone on a forum recommending topical delay products, so I thought I'd give it a shot—after all, topical application feels safer than oral medication.

After comparing options, I ended up buying the Japan Biteiting Men's Endurance Gel 2H2D Delay Liquid Adult Products Male Delay Spray. What attracted me was the Japanese brand and the gel texture—unlike sprays that tend to drift in the air, it should be easier to control the dosage.

The first time I used it was after a shower at night. Following the instructions, I applied it 20 minutes before intercourse. It came out as a clear gel with no noticeable smell. I applied it to the glans and the coronal sulcus. At first, it felt a bit cool, but after a few minutes, the sensation faded. Then I just waited—honestly, those 20 minutes were pretty nerve-wracking, and I was afraid it wouldn't work.

When the time came, it felt about the same as usual at first, but after about 5 minutes, I realized I wasn't as sensitive as before. It wasn't completely numb, though—I could still feel the stimulation, but I didn't get that immediate urge to finish. That session lasted about 20-plus minutes, which was much longer than usual, and my wife was pretty satisfied.

I used it several more times afterward and figured out some patterns.

Onset time: If used on an empty stomach or after a shower, I'd feel the effect in about 15-20 minutes. If I'd eaten something greasy, it could take over 30 minutes. Once, after eating hot pot, I waited nearly 40 minutes before it kicked in.

Duration: For me, the effect lasts about 3 hours, but it's not equally strong the whole time. The first hour is the most noticeable, and then it gradually fades, but it's still much better than without it.

Side effects: To be honest, the first two times, my glans felt slightly warm, but it went away quickly. There was no numbness or pain. I saw some people online mention numbness, but maybe it's because I used a conservative amount—just a pea-sized squeeze each time. I started small and gradually found the right dosage for myself.

As for drawbacks, I have to mention two things.

First, this gel doesn't absorb very quickly. You have to wait 20 minutes after applying, and it's best not to wear underwear during that time, or some of it will rub off—which is a hassle. Once, I forgot about the timing and put on pants right away, and the effect was significantly reduced.

Second, the price isn't cheap. A 15ml bottle lasted me about a dozen uses, which works out to over 20 yuan per use. Using it long-term does sting a bit financially.

Later, I tried a few other products and here's a simple comparison:

Additionally, I've been pairing it with 2H2D Black Maca Authentic 120 Capsules Delay and Hardness Enhancement Maca Tablets, and I feel like my stamina has improved, though I'm not sure if it's just a placebo effect.

Now, let's talk about who this is suitable for.

If you're only occasionally off your game or want to enhance the experience, this 2H2D gel is a great fit—gentle, non-irritating, and it won't dull the sensation. But if you have severe premature ejaculation or you're chasing that "iron rod" effect, this might not be strong enough. In that case, you could consider the Japan 2H2D Black Gold Edition Endurance Spray, which is said to be more potent.

One final reminder: topical delay products are only a supplement—they can't solve the root problem. If you're consistently underperforming, it's best to see a doctor. Adjusting your routine and exercising are the real solutions.

Alright, that's all I have to say. I hope this helps anyone dealing with the same issue.
