How to Choose an External Prolongation Spray? There are so many brands on the market that it's overwhelming, and the marketing claims get wilder by the minute, but the one that truly suits you might just be one or two options. This time, I've put together a side-by-side comparison of Germany's EROS Ilusion 101, Germany's Black Diamond, Japan's 2H2D Black Gold Edition, and another popular internet-famous product, evaluating them across five dimensions: ingredients, onset time, duration, side effects, and price. My goal is to help you avoid wasting money on the wrong choice.

Key Takeaway First: Different Needs, Different Products

Seeking a natural experience and worried about numbness: Prioritize Germany's EROS Ilusion 101. It's made from pure plant extracts, contains no anesthetics, and offers the most realistic sensation.

Need fast onset for last-minute situations: Germany's Black Diamond works the fastest, kicking in around 8 minutes, making it ideal for unplanned scenarios.

On a budget and looking for overall value: Japan's 2H2D Black Gold Edition is affordable, with balanced prolongation effects, suitable for regular use.

Want strong prolongation and can tolerate some numbness: The other internet-famous product (I won't name it here) delivers noticeable prolongation, but the numbness is also significant, making it best for those who prioritize duration above all else.

Detailed Product Reviews

Germany's EROS Ilusion 101: Top Pick for the Natural Camp

This is my personal favorite, and the reason is its very clean ingredient list. The official website clearly states it contains no lidocaine or benzocaine, instead using natural ingredients like clove essence to prolong time by reducing sensitivity, rather than numbing the nerves. In actual use, there's no noticeable sensation when sprayed, and it takes effect after 30-40 minutes. Throughout the process, you barely feel its presence, but the time is indeed extended—from a few minutes to about 20-30 minutes.

Advantages: No numbness, full preservation of pleasure; water-soluble, easy to wash off; German original, guaranteed quality; 30ml large capacity, great value.
Disadvantages: Slow onset, requires preparation 40 minutes in advance; may still irritate sensitive skin, so a small patch test is recommended; slightly higher price than similar products.

If you're after a natural, healthy experience and don't want to sacrifice pleasure for numbness, this one is well worth considering.

Germany's Black Diamond: Savior for Quick Finishers

Germany's Black Diamond's biggest selling point is speed—it takes effect just 8 minutes after spraying, making it perfect for spontaneous or unplanned situations. Its prolongation effect is also solid, extending time by 20-30 minutes, but some users have reported a slight burning sensation, and the lack of ingredient transparency is a bit concerning to me.

Advantages: Extremely fast onset, great for emergencies; noticeable prolongation effect; moderate price.
Disadvantages: Unclear ingredients, may contain alcohol; mild numbness and burning sensation; small capacity (10ml), so per-use cost isn't low.

If you need it for last-minute situations or frequently face unexpected moments, it's worth keeping a bottle on hand, but make sure to do a skin test first.

Japan's 2H2D Black Gold Edition: The Balanced Choice

2H2D has a solid reputation in men's health circles, and this Black Gold Edition is an upgraded version with more added herbal ingredients. In actual experience, onset takes about 15 minutes, and the prolongation effect lasts about 40-60 minutes—slightly weaker than EROS but more enduring than Black Diamond. There's a mild herbal scent, but it fades quickly and doesn't affect the experience. It's the cheapest of the three, offering excellent value.

Advantages: Affordable price; balanced prolongation effect; relatively natural ingredients; moderate capacity.
Disadvantages: Mild numbness; moderate onset time; the herbal scent might not appeal to everyone.

If you're trying an external prolongation spray for the first time or have a limited budget, 2H2D is a great entry-level option.

Internet-Famous Product (Unnamed): Proceed with Caution

These products usually have aggressive marketing, but the actual ingredients are often just alcohol plus anesthetics. They work fast but come with strong numbness, significantly diminishing pleasure. While they're cheap, the experience is poor, and long-term use may irritate the skin. I personally don't recommend them, unless you only care about prolonging duration and don't mind the downsides.

Advantages: Low price; fast onset; noticeable prolongation.
Disadvantages: Strong numbness; opaque ingredients; potential side effects; reduced pleasure.

Recommendations by Scenario

Seeking a natural experience and prioritizing pleasure: Go with Germany's EROS Ilusion 101. It's pricier, but worth every penny.

Last-minute needs and fast onset: Choose Germany's Black Diamond—it works in 8 minutes, but watch out for the burning sensation.

Regular use on a budget: Pick Japan's 2H2D Black Gold Edition—the king of value.

First-time trying and unsure if it suits you: Start with a small bottle, like 2H2D or EROS, to test your skin's reaction.

Usage Precautions

1. Always do a skin patch test first: Spray a small drop on your inner arm or behind your ear, and wait 24 hours to check for redness or swelling before use.
2. Stick strictly to the recommended dose: Start with just one spray for the first use—don't overdo it. You can add more if the effect isn't enough.
3. Avoid spraying on the urethral opening: This can cause stinging. Instead, spray on the coronal sulcus of the glans and spread it evenly with your hand.
4. Plan ahead: Especially for slow-onset products like EROS, apply 30-40 minutes in advance.
5. Don't mix with oral medications: Using external sprays and oral drugs (like Viagra) together may increase cardiovascular strain. Leave at least 12 hours between them.
6. Cleaning: If oral sex is involved, wash the penis before use, or choose a water-soluble formula (like EROS) that's easier to clean off.

FAQ

Q1: Are external prolongation sprays safe? Can they cause dependence?

External prolongation sprays mainly contain plant extracts or local anesthetics that act on the surface without entering the bloodstream, so they're generally safe. Legitimate products won't cause dependence, but long-term use of those with anesthetics may reduce sensitivity. It's recommended to rotate products or choose ones with natural ingredients.

Q2: Why do some sprays make me feel numb?

Numbness usually comes from anesthetic ingredients (like lidocaine), which prolong time by blocking nerve signals but also reduce pleasure. If you want to avoid numbness, choose products without anesthetics, such as Germany's EROS Ilusion 101.

Q3: Can external prolongation sprays treat premature ejaculation?

No. External sprays only temporarily extend ejaculation time and don't address the root cause. If premature ejaculation is severe, consult a doctor—oral medications or behavioral therapy may be needed.

Q4: Do external prolongation sprays affect fertility?

There's currently no evidence that external sprays affect sperm quality or fertility, but those containing anesthetics may reduce ejaculation pleasure, indirectly impacting conception. It's advisable to use them cautiously when trying to conceive.

Q5: Can I use them every day?

Daily use is not recommended. Frequent use may lower local skin sensitivity and even cause allergies. Limit use to no more than 2-3 times per week to give your skin time to recover.

Conclusion

When choosing an external prolongation spray, the key is your core need: Do you want natural or fast? Value or maximum potency? There's no absolute good or bad—only what fits you best.
