Stud 100 is a strong desensitizing spray that consistently helped me last several minutes longer during sex. It’s a convenient treatment for premature ejaculation that’s easy to use, takes action quickly, and is available without a prescription.
As with all delay sprays, you might get a tingling sensation from the lidocaine or have difficulty maintaining an erection if you apply too much. So it’s a good idea to start with a small amount until you find the dose that works best for you.
- Strong numbing helps you cope with the physical stimulation of sex.
- Only need to apply it 5-15 mins before sex.
- Metered pump gives consistent doses.
- Can be used with oral sex.
- Can be used with or without a condom.
- Available without a prescription.
- Low cost per spray.
- Some initial trial and error is needed to get the dosage right.
- May reduce some pleasure.
- Can be difficult to get an erection if you use too much.
- Can give a tingling sensation.
- Not a permanent cure for premature ejaculation.
I ordered a bottle of Stud 100 from Amazon, which seems to be the main site it’s sold on and the price was very reasonable at under $15.
I was pleased to see that the bottle has a metered pump so you can apply a similar amount each time. Not all sprays (and no gels) have this useful feature to help you get the dosage right.
I sprayed the head of my flaccid penis once and gently rubbed it in, paying attention to the tip and frenulum which is where I’m most sensitive. I waited for 10 minutes, then wiped myself with a damp cloth to remove any residue.
I could definitely feel a good amount of numbing even before the 10 minutes was up. The numbing sensation of Stud 100 seemed similar to most other strong lidocaine sprays I’ve used, which isn’t a surprise as many of them use the same active ingredient.
My partner is always up for trying new sex products with me, so once the 10 minutes were up, we got down to some testing.
It helped me last a few minutes longer
Stud 100 worked well the first time we had sex using it, helping me last several minutes longer. One evening later that week, I was able to last more than 10 minutes, which is a considerable improvement on my usual under five minutes.
I was still able to feel pleasure, which is of course very important. However, the sensation was considerably dulled on the penis head with the numbing. That always happens with lidocaine sprays and is to be expected.
There’s always a trade-off between pleasure reduction and longer sex with these sprays, so on the whole I was happy enough with Stud 100. There’s more to sex than just the physical pleasure you feel on the tip of your penis.
For me, it’s very important to be able to give my partner the chance to enjoy longer sessions of intercourse. She agrees, of course.
Getting the right dosage
I also experimented with two and three sprays on different days. Two was ok, but perhaps a little too strong. Three was total overkill, making it difficult to get an erection, especially when I rubbed it into the shaft as well.
So personally, one spray is the sweet spot for me, which is good as it means the bottle will last longer. The dosage will vary from person to person though, so you might find you need two, three, or even more sprays. It’s why I suggest experimenting on your own first, as you don’t want to use any more than is necessary.
Fine for oral and condoms
Stud 100 has a light smell, which all lidocaine sprays do. If you’re worried about it, have a shower instead of just wiping off the excess. As long as you wait a few minutes for it to absorb, even a long shower won’t stop the numbing effect and it will get rid of any lingering smell.
It was also fine for oral sex as long as I wiped the excess and waited for it to absorb. My partner had no complaints about the smell or taste, and didn’t feel any numbing to her mouth.
You can use Stud 100 with or without a latex condom, which is always a plus from this type of spray.
All lidocaine sprays give me a bit of a tingling sensation, but it’s usually mild. Nothing as extreme as some of the more unusual products that give you a “get it off me!” feeling.
So all in all, Stud 100 was at the light tingling end of the spectrum and was tolerable.
Stud 100 worked for me in a similar fashion to the other good delay sprays that use lidocaine as the active ingredient. Like Promescent, Dynamo, and K-Y, I think it’s one to try if you need to reduce your sensitivity.
It’s good that it has the metered pump, you can still have oral sex, and it’s fine with or without a condom. These are some of the basic usability points I look out for.
Unlike some of the less impressive sprays out there, it absorbs quite well and doesn’t have too much of a chemical smell, so you can use it fairly discreetly before you have sex.
One final point in its favor is that it’s not as expensive as some of my other top-rated sprays. So if you’d like to test a decent spray without spending too much money, Stud 100 is a good choice.
Who makes Stud 100?
Stud 100 is manufactured in the U.K. by Pound International. They’ve been making and selling it since the 1970s, making it the oldest desensitizing spray I’ve seen.
Stud 100 Ingredients
- Lidocaine Base USP 9.6% (the active ingredient)
- Isopropyl Myristate
- Stearic Acid
- 2-(2-Ethoxyethoxy) ethanol
Is it safe?
The manufacturer states that Stud 100 is FDA compliant, meaning they adhered to the standards set for male desensitizing sprays. It hasn’t undergone clinical trials though, so there is no official safety data.
The manufacturer also says it’s safe for use during oral sex. But be sure to wait at least 10-15 minutes after application to avoid the risk of numbing your partner’s mouth.
Lidocaine can on rare occasions cause problems for some people. Stud 100 is unlikely to cause any problems at such small doses, but be careful not to use too much of it in one session.
Finally, if your partner is pregnant or you’re trying to conceive, I wouldn’t use this or any other desensitizing spray.
How long does it last?
I found it lasts for up to two hours. This will probably vary from person to person. It means you can apply it long before you have sex if you like, which helps reduce the mood killer of having to stop to apply the spray just when things are heating up in the bedoom.
How do you use it?
You’re supposed to spray it onto your penis head (the exposed head). Rub it in, then wait 5 to 15 minutes. You can also spray the whole shaft if you think it will help better. Some trial and error is always a good idea to find the balance between numbing the sensitivity and not killing your erection completely because you can’t feel a thing.
Personally, I think it’s a good idea to wipe off any excess, especially if you have oral sex or don’t use a condom.
You can use a damp cloth or towel, your hand and running water in the sink, or have a shower. It doesn’t matter what you do as long as you get rid of any liquid that didn’t absorb before you put it in contact with your partner’s sensitive areas.
Can a woman use stud 100 spray in or around the vagina without any side effect?
I think the effect would be numbing that they may or may not like. I don’t know if it can cause other side effects.
Hi my penis is very sensitive, so sensitive I cant receive a blow job. Wondering if the numbing will allow that now?
Ideally, yes. But since different men react differently, and to different sprays, it’s kind of hard to predict whether you will be able to do exactly what you want. Hopefully, it will work for you, but you’ll just have to try it really.
I just wanted to know if we put 4 doses of spray, how much time we will I get?
It’s impossible to judge. But increasing the number of doses doesn’t automatically mean you will get even more time. It’s all about finding the right balance between numbnig you enough to last longer, but not so much that you can’t maintain an erection or enjoy sex.
Do you apply to erect penis or soft penis?
Either is fine, but flaccid might be easier if you need to wait for it to work. But if you find it makes it difficult to get an erection afterwards, try putting it on the erect penis instead.
My partner and I are trying for kids and I use the Stud 100 regularly & has worked very well for me but just wanting to ask if the Stud 100 spray affects my partner falling pregnant or is it only an issue when she is pregnant??
They normally say not to use these sprays when trying for a baby or when pregnant. So for now, I would avoid it.
Benji how much time it works… For 20 or more you experienced?
When applying stud 100, is unprotected sex dangerous? or do you still feel that urge when cumming? and does it give you time to take your penis out of the vagina?
I don’t think it’s dangerous as long as you make sure there is no residue so you don’t numb your partner. Yes you can still feel the urge. And you should have time, but that depends on you I guess, as different people have different levels of awareness about when it’s approaching.
How long does the numbing effect last for.. so can I put it on then have sex 3 hours later and still be fine?
It might still work a bit, but you’d need to experiment. For me, two hours is the time it starts to reduce in effect.
Sir after applying stud 100, after 10 min before sex I should wipe with a cloth, or else I should make that cloth into wet and wipe, like should wipe with a little water?
It’s up to you. Either should be fine. Personally, if I’m having unprotected sex, I use some water just to make sure it doesn’t transfer and numb my partner.
I used it before, I tried with 1 spray in the soft area not in the head, I used it for only oral and that time I didn’t get good feel like normal but it was delayed and kept me on more time, so my question is,
1. It can be spray only on the skinless head instead the whole penis?
2. After 15 minutes and wiped out, I can go for direct intercourse without latex? – Means it is safe to my partner?
3. While using without latex, Is it safe to a woman approaching pregnancy?
1. It’s your choice. It’s fine to experiment and see what works best.
2. Yes that’s fine.
3. Usually they say no.
Seems like I didn’t use stud 100 correctly. I think I put a lot of spray in a session so it’s difficult for me to get an erection. What should I do please?
Either use less next time, or try a different spray.
I am awaiting my stud 100 supply. It may arrive tomorrow. My question:
If I have sprayed stud 100 on my penis and suddenly sex is called off for the night due to unforeseen circumstances, is there a problem?
I hope the spray works well for you (and that sex is not called off!).
There is no problem regarding the spray. You will probably feel numb down there, but it should go away naturally without any issues.
I received my supply of Stud 100 on 16 February 2019. The first time I used it I sprayed twice, I have no problem to get a hard erection and I did not feel any tingling sensation or numbness even after 30 minutes but the sex was just about 5 minutes. At 1.30 am I was awakened by the tingling sensation but managed to sleep back.
The second time I sprayed three times and I had a hard time to get an erection and when I finally got the erection, it was not so hard and sex lasted just about 5 minutes. There is no tingling sensation or numbness.
In view of the unfavorable experience of not getting an erection instantly as it used to be, I stopped using stud 100 just after two times. I was dead worried that I might not get an erection at all.
I don’t drink or smoke and I really take care of my diet. Along the way, I read one’s man comment that he can only last long in bed if he was drunk. I search online about the type of wine that increases sex drive. I found out that Red Wine was great for sex. I purchased a bottle of red wine with 14% alcohol contents and I drank about 50 ml only just before I had sex with my wife. Interestingly, I lasted about 40 minutes in bed with steel hard erection for the very first time since so many years. Since then my sex life is now on cloud nine and every morning I got morning wood which was rare in the past.
For me, Red Wine is the answer to my acute premature ejaculation problem. I drank red wine for sex and it works fantastic for me.
Thank you for sharing your experience. First of all, sorry to hear the spray wasn’t right for you. Secondly, I’ve also found alcohol in the right amount can be very effective for PE. Too much and erection problems can happen again, but just the right amount seems to help a lot.
Hope your hands still work! lol
Hi, I used this stud 100 spray a couple of times, and once I felt like dizzy and a bit of a headache at the same time. I might have sprayed a bit too much. Suggestions please!
Sound to me like you already know what to do – spray less! One technique to apply only a tiny amount is to spray it into your hand, or even a glass, first. then dip your finger in and just apply the amount to your penis that sticks to your finger, and wash the rest off.
Thank you for this review. I have just ordered from boots and awaiting arrival. I am not circumcised and plan on applying 1-2 sprays before I become erect therefore pulling the foreskin back can be somewhat painful, even when erect. I usually just let it naturally come back during sex. Would it still be effective if just sprayed on the external head whilst my foreskin is covering?
You are very welcome! I hope it works out well for you. It shouldn’t be painful to retract your foreskin. Have you spoken to a doctor about that? Perhaps you could have a shower to loosen it up and then apply the spray to the head when you’re out. It might help a little to spray on the external head that you can see, but ideally, it’s good to get the whole head and especially the frenulum sprayed.
Thanks for the post. I have a question
when should this be applied? Can this be applied before the fore play when one is not that erect? And still get an erection normally one gets during the fore play?
You’re very welcome! Yes, you can apply it before you even start foreplay if you like. It should last for at least an hour. You can get an erection as long as you don’t apply too much of it. Some men have no problem getting an erection with a delay spray, others find it a problem. So my advice is to experiment with just a small amount on the penis head to start with.
Using stud 100 could my partner fall pregnant, is pregnancy possible?
Yes, it is possible. But they don’t recommend trying when you use the spray.
Is it possible to do oral sex?
Yes, as long as you wipe/wash first to remove any of the product after it has been absorbed.
How long does it stay numb after you spay it on?
It depends on how much you put on etc. But in my experience, this and other lidocaine sprays usually last a couple of hours.
Which is better sir? Spraying on the head and shaft of the penis or just the head
In my experience just the head. If you spray the entire penis, the risk is you’ll feel no pleasure. You can experiment if you like, but I think it’s good to numb the head and keep full sensitivity for the shaft. But if that’s not enough for you, and you’re still too sensitive when you have sex, you might like to spray the entire penis to see if that works out better.
Is there any serious side-effects after applying the stud 100, and in period of waiting for the spray to absorb….then something happens like emergency call or any other thing interrupting that moment, then my partner is no longer in the mood for sex, what should be done in that case?
Most men have no problems. Very rarely there might be a reaction to the lidocaine ingredient, like serious burning sensation or a rash.
If you are interrupted it’s no problem. You can carry on your normal day, just with a numb penis in your pants!
I want to know if after I sprayed the stuff and waited 15 minutes before sex, should I wash the penis or wipe it with a wet towel or not?
Minimum 3 sprays before sex?
How much time can I have sex after using spray?
Drinking alcohol before or after using spray, and during sex, can affect me in some way?
1. Wash or wipe is fine.
2. I would use 1 spray to start, add more next time if needed.
3. I thnk 10-15 mins.
4. Alcohol should be fine.
It’s not a cure, so you’ll have to use it every time you have sex. What does that mean? does it mean that if I used it one time I have to keep using it every time I wanna have sex?
It just means it only works when you use it. You can’t spray once and then never have premature ejaculation again. But it doesn’t mean you must use it forever just because you used it once either. It’s a choice.
Devo aplicar o stud 100 entre 5 a 10 minutos antes de ter relações com o pênis eréctil ou flácido.
Não importa se é ereto ou flácido – você pode decidir com base no que funciona melhor para você.
Hi, if I go out, can I apply stud 100 like 2 hours before sex? don’t want to apply it on when the other person is there.
Great question! This idea is something I might write about soon – how to use products like these in as subtle a way as possible.
I think the key is to experiment yourself at home first. Apply the spray, and time how long your penis stays numb for. Get a sex toy or just masturbate normally to see if the effect is still good after 1, 2, 3 or more hours. Then you can work out how long your window is between going out and having sex.
Otherwise, just pop into the toilet before sex and spray it subtly.
