First, let me give some background. I'm 41 this year and work in sales, so I have a lot of social engagements and high pressure. Over the past two years, I've clearly felt that my condition isn't what it used to be. I used to take an oral product, but sometimes things come up at short notice and there's no time to take it in advance, so I wanted to find a topical product to have on hand. There are plenty of these products on the market, and I've tried three so far: Germany's EROS Yilusi 101, Germany's Black King Kong, and the one I'm focusing on this time, the Clee men's endurance spray.

I first bought Clee because I saw it advertised with two functions—"delay + erection support"—and the spray format is more convenient than drops. The price is mid-range, and one box can be used quite a few times, so I placed an order.

First use: a bit of a scramble

I tried it the same night it arrived. After showering and drying off, I sprayed it twice near the coronal sulcus. The instructions say to spray 1–2 times, and the first time I didn't dare spray more. It felt cool when applied and wasn't irritating.

After about 15 minutes, I started to feel something—not the kind of numbness where you lose all sensation, but a reduction in sensitivity while touch was still there. That night it lasted about an hour and a half, which was indeed longer than usual. But there was a problem: the nozzle is press-type, and the first time I didn't control it well and sprayed a bit too much, which made the front area overly numb and took away from the experience. I learned my lesson in later uses: spray once each time, wait 5 minutes, then add half a spray more, and the effect was much better.

Observations after four or five uses

Onset time: about 15–20 minutes on an empty stomach or after a shower; if I'd just eaten something greasy, it might take more than 25 minutes. Once I used it after hot pot and waited almost half an hour before I felt anything.

Duration: based on how it felt to me, a single use lasted about 1.5 to 2 hours. Two sprays lasted slightly longer than one, but it didn't double.

Side effects: I used it about seven or eight times and didn't experience burning or redness and swelling. Twice, when I sprayed too much, the area felt a bit numb, and it recovered after washing off. Compared with a benzocaine-containing product I'd used before, Clee's numbness is on the milder side.

Erection support: to be honest, I didn't notice any obvious erection-enhancing effect. It may contain some ingredients that promote blood circulation, but I don't have any problems with erectile function myself, so this doesn't mean much to me. If you have trouble with erection hardness, I'd suggest not expecting a bottle of spray to solve it.

Things I'm not satisfied with

First, the nozzle design. The press-type nozzle is hard to control in terms of force; sometimes what comes out is a stream rather than a mist, and it easily runs down and goes to waste. Later I sprayed it into my palm first and then applied it, but that lost the convenience of a spray.

Second, the effect is reduced after washing off. Once I took a shower midway after using it, and when I continued afterward, the effect felt much weaker. So it's best to use it in situations where you're sure you won't wash it off midway.

Third, the packaging is a mix of English and Japanese, and the Chinese instructions are stuck on, which doesn't look very formal. Although the anti-counterfeiting code can be checked by scanning, the first impression is so-so.

Side-by-side comparison of the three products

If you're after strong, long-lasting effects, Black King Kong may be more suitable; if you want fast onset and don't mind numbness, EROS is good; if, like me, you want something mild and natural, easy to use, and moderately priced, Clee is worth a try.

About ingredients and how they work

I've looked up some information. These topical endurance liquids mainly fall into two categories: one is surface anesthetics (such as lidocaine and benzocaine), which delay ejaculation by reducing glans sensitivity; the other is plant extracts (such as clove, maca, ginseng, etc.), which improve condition by promoting blood circulation and providing mild stimulation. Clee's ingredient list contains both plant extracts and a small amount of anesthetic ingredients, so the feel is somewhere in between.

One reminder: no matter which ingredient it is, the first time you use it you should test a small area first and confirm you're not allergic before using it. Also, after spraying, it's best to wait a few minutes before starting so the ingredients can absorb; otherwise it may rub off onto your partner.

Common questions

Q: Do I need to wash it off after spraying?
A: Check the product instructions. Clee recommends washing it off after 10 minutes or going ahead directly; if you don't wash it off, your partner may feel slight numbness.

Q: Can I use it every day?
A: Not recommended. Frequent use of topical anesthetic products may reduce sensitivity; two or three times a week is more appropriate.

Q: Can it be used together with oral medication?
A: It's best to space them out or consult a doctor. Using topical and oral products at the same time may stack side effects.

Who it's suitable for and who it isn't

Suitable for: beginners just starting to try topical delay products; people who are sensitive to numbness and want a natural feel; people with a limited budget who want to give it a try.

Not suitable for: veterans chasing extra-long endurance (more than 2 hours); people with obvious problems with erection hardness (spray can't solve that); people who lack patience for nozzle operation and prefer something simple and direct.

One last thing: these products are only an aid, and condition has more to do with rest and mindset. Don't pin all your hopes on a bottle of spray.
