Eight out of ten first-time buyers of delay sprays make the same mistake: they only look at the word "lasting" and ignore the ingredients and source. I was the same back then—I bought a knockoff product for just over thirty yuan because it was cheap. After spraying, it was indeed "lasting"—so numb that I felt nothing for hours, and the experience was completely ruined. Later, I tried seven or eight products one after another, including BOSO, EROS 101, and Black King Kong, and gradually figured out the tricks. This article breaks down the pitfalls I've encountered one by one, so you can avoid them by comparison.

Pitfall 1: Buying fakes or anesthetic-adulterated products to save money

This is the most deadly pitfall. The core ingredients of topical delay liquids are usually local anesthetics such as lidocaine and benzocaine, and they are only safe at compliant concentrations. To make you "feel it works," fakes often add excessive anesthetics—after spraying, it feels like you're in a cast, all pleasure is gone, and long-term use may even affect normal function.

How to identify:

How to avoid: For your first purchase, stick to flagship stores or authorized channels, and don't order from unknown individual shops. I later settled on BOSO delay spray because its channels are relatively transparent and its nozzle is fine, making it hard to over-spray in one go.

Pitfall 2: Spraying heavily right away, losing control of the dose

Many people think the more they spray, the longer it lasts, but the result is either numbness to the point of no sensation or inability to get hard. Absorption of topical delay liquids varies from person to person. For beginners, it's recommended to start with 1-2 sprays near the coronal sulcus (not the center of the glans), wait 10-15 minutes for the skin to absorb it, and then assess the effect. Add one more spray if needed—never go with five or six sprays at once.

My own experience: two sprays of BOSO can extend it to roughly 20-30 minutes, and beyond that the numbness increases noticeably. The German Black King Kong product focuses on not numbing; in actual use the numbness is indeed lighter, but the extension is also relatively mild, suitable for those who don't want to sacrifice sensation. For specific sensory differences, you can refer to the Cool Love spray sensory experience article, which goes into more detail.

Pitfall 3: Using it immediately after spraying, without waiting for absorption

This is the number one reason for "it didn't work." If you go right into action after spraying, the liquid hasn't penetrated the skin yet and rubs off with a couple of strokes—equivalent to spraying for nothing. The correct approach is to spray 15-20 minutes in advance, let it sit, and allow it to absorb naturally. If you're in a hurry, you can gently massage to help absorption, but don't rub hard.

Also, it's best to wash your hands after spraying before touching your partner, to avoid transferring the anesthetic to them and causing discomfort. Many people overlook this detail, but it's quite important.

Pitfall 4: Not washing, leaving numbness the next day

Topical delay liquids aren't done once you spray. If you don't want to affect sensation during action, you can gently wipe off surface residue with a wet wipe 15 minutes after spraying, keeping the absorbed part. After finishing, it's recommended to wash with warm water—especially for those with a longer foreskin, residual liquid will continue to cause numbness; if you still feel "no sensation" the next morning, you didn't wash it off properly.

BOSO has a more watery texture and is easier to clean than some oil-based formulas. Black King Kong is also water-based and easy to rinse. If you use an oilier or stickier product, clean more carefully.

Pitfall 5: Ignoring safety contraindications and pushing through

Although topical delay liquids are only for local use, they're not suitable for everyone. Consult a doctor before use in the following cases:

One more point: delay sprays are auxiliary tools, not treatments. If premature ejaculation persists and affects your life, see a doctor—don't expect a bottle of spray to solve everything.

How to choose by budget and needs

Under 100 yuan, first try: Prioritize small-capacity or entry-level products, focusing on legitimate channels and clearly labeled ingredients. Don't chase words like "super strong" or "macho"—mild products are better for beginners to build sensory awareness.

100-200 yuan, seeking a stable experience: This range has the most choices. BOSO delay spray is a balanced type, with extension time and numbness control fairly balanced, and a fine nozzle for easy dose control—suitable for daily use. EROS 101 is somewhat stronger, suitable for scenarios requiring longer time, but numbness will be slightly more noticeable. For those who want both effect and sensation, check out Black King Kong delay liquid—it focuses on not numbing, with actual extension of about 15-25 minutes, suitable for people sensitive to numbness.

Above 200 yuan: At this price point, it's mostly brand premium and packaging experience; the core ingredients aren't much different from the 100-yuan tier. Unless you have a clear preference for a certain brand, there's no need to chase higher prices. For a side-by-side comparison, see Delay liquid comparison, which lists the onset and duration times of several products fairly clearly.

A few final honest words

With topical delay liquids, effects vary from person to person—others say it extends by half an hour, but you might only get十几 minutes; that's normal. The key is to buy a small package first, find the dose and style that suits you, and don't stock up on big bottles right away. Keep these three points—legitimate channels, clear ingredients, controllable dosage—and you basically won't fall into big pitfalls. As for those that are hyped to the skies and sold dirt cheap, just steer clear.
