Can you get an STI from a used sex toy ?

Do you mean when sharing a toy during sex, or when buying a used toy ?


Good news - time can be on your side when you´re buying a used one.

¨…most pathogens that cause STDs cannot live outside of the human body for very long without deteriorating. Once bacteria and viruses start to break down, they are no longer able to infect human beings…¨


Buying vs. Sharing

Buying a sex toy second hand is quite a new thing, so most of the current answers you read online are all about the risks of sharing a toy in the heat of the moment during a sex session, not about buying one second-hand – one that has been cleaned first, disinfected or sterilized, and then packaged up, and sent by post to you.


Everyone has an opinion, or an agenda.

If you ask everyone, you´ll get answers all the way from a yes depending to a no depending. And still, you´re none the wiser, really. Believe me, we have circled the internet and asked around – everyone has an opinion, or an agenda!

And are you even asking the right questions ? This article is about buying a used sex toy, and we´ve used the officials and experts to provide the answers,  but if you want to know what they say about the risks of sharing one during sex, jump to the answer here. We have a couple of blog posts that might be useful – What makes a sex toy body-safe, and an FAQ covering some of the more common questions.


Myth vs. Fact

In the great echo chamber that is the internet, some detail gets lost, and a general opinion just hangs around with no real purpose. And we´re left asking – are the risks actually real any more, or just perceived ? When discussing this very subject, states the difference for us.

¨A perceived (or theoretical) risk is one that is based on belief rather than fact and persists despite the unlikeliness of the event ever occurring. By contrast, a documented (or actual) risk is based on statistical evidence of something actually occurring. Where a perceived risk is about theory, a documented risk is about the fact.¨


We all take risks with germs every day, and more when we go to public places, to hospitals, or have any invasive procedures. So the medical community have this covered, and are monitoring it all the time. Like a dog with a bone, we were determined to get to the facts.

Ask the right questions. Get the full story. Listen to the experts.


If we´re all grown-up enough to play with sex toys, we need to get practical about this really important subject.

We´ll get right down to the nitty-gritty here, with some really specific questions, to see what the medical specialists, the official government or health organisations say about this.


This answer tells us first, that if you´re buying one, use TIME to be on the safe side. 

Question: How Long Can STD Viruses or Bacteria Survive Outside the Body?

Answer: ¨Most STDs cannot survive for very long outside of the human body. Let’s look through some common sexually transmitted diseases and take note of how long each can survive without a human host.

Chlamydia: This STD can only survive outside of a human body for two or three hours. Since it requires particularly humid conditions and can’t live for long without a host, it’s unlikely that chlamydia could spread via contact with clothing or other surfaces.

Gonorrhea: The gonorrheal bacteria can only survive for a few minutes without a human host, so it’s extremely unlikely for gonorrhea to spread through contact with affected surfaces or shared clothing.

Hepatitis B: The Hep B virus can survive for as long as a week without a human host. During this time, a non-infected person can contract this disease.

Hepatitis C: The Hep C virus can actually live for up to three weeks without a human host, as long as the environment is hospitable to it (around room temperature). This disease is among the easiest to contract without the need for sexual contact between an infected and non-infected person.

HIV: The HIV virus cannot survive very long without a human host and the ability to reproduce. After minutes or hours, HIV will die on an inanimate surface.

Syphilis: This disease can only survive for very brief periods of time outside of the human body. Syphilis most commonly spreads through direct sexual contact.

HPV: Human papillomavirus cannot survive for very long outside of a host, so it’s nearly impossible to contract this disease from contact with a toilet seat or similar surface.



Let´s go deeper – take any risk away – make it clean and sterile

Why ? Because the right cleaning, disinfecting or sterilizing can get rid of any possible germs too. So, even we´ve looked at sexually transmitted infections / diseases, and how the experts say you can kill them off surfaces. Remember always clean first, then sanitize, then disinfect, then sterilize. Also, remember that toys made of non-porous materials ( e.g. silicone, glass, metal ) will be easier to clean thoroughly.

How to avoid getting germs from a sex toy.

1. Know the possible STIs. Face it, even if the risk is tiny.

2. Learn how long they last outside the human body.

3. Discover what kills them ( if time has not already done the job for you ).

What are the STIs / STDs ?

The two terms tend to be used interchangeably but one stands for ´sexually transmitted infection´ and the other stands for ´sexually transmitted disease´. Let´s name them.

¨STDs can include bacterial, viral and parasitic infection. Bacterial STDs include chlamydia, gonorrhoea, and syphilis. Viral STDs include HIV, genital herpes, genital warts (HPV), and hepatitis B. Trichomoniasis is caused by a parasite.
The germs that cause STDs hide in semen, blood, vaginal secretions, and sometimes saliva. Most of the organisms are spread by vaginal, anal, or oral sex, but some, such as those that cause genital herpes and genital warts, may be spread through skin contact. One can get hepatitis B by sharing personal items, such as toothbrushes or razors, with someone who has it.¨



This type of germ lasts the shortest time, but washing your sex toys with warm water and unscented soap, or with a specific sex toy cleaner, then rinsed and air dried is good practice to keep your toy clean here.

This type of germ can last longer so  level 2 or preferably a level 3 disinfectants or sterilization like bleach seems to be the way to get rid of these. Read on for the detail and references.




¨In general, the virus doesn’t live long once it’s outside of a human body. Studies show that HIV grown in the lab, when placed on a surface, loses most of its ability to infect — 90% to 99% — within several hours

¨Under specific conditions, HIV can survive outside of the body for hours or even days if the temperature, humidity, UV exposure, and pH balance are all just right. It is a very unusual set of conditions but one that is, in fact, possible. ¨
¨Unless all of these conditions are satisfied, an HIV infection simply cannot occur¨


Use a level 2 (intermediate)  or 3 (high level) disinfectant.

¨EPA-registered tuberculocidal disinfectants are best for cleaning surfaces contaminated with blood.
Disinfectants that kill the bacteria that cause tuberculosis can also kill HIV, hepatitis B and hepatitis C viruses.¨

( Note: there are 3 levels of disinfectants – the one referred to here are level 2 / intermediate level.)

“The EPA has a web site listing all EPA-registered tuberculocides and disinfectants that are effective against HIV and HBV.”



Also known as Hep-B


¨Can vibrators and sex toys spread hepatitis? That’s possible, because the hepatitis B virus can survive outside the body for a week or more. Immersing the vibrator in boiling water may reduce the risk.19 Jun 2020


¨Bleach is a wonderful disinfectant, and effectively kills HBV, and other pathogens.¨

¨The CDC recommendation for high-level disinfection of HBV-, HCV-, HIV- or TB-contaminated devices is appropriate because experiments have demonstrated the effectiveness of high-level disinfectants to inactivate these and other pathogens that might contaminate semicritical devices.¨




Also known as genital herpes.

How long HPV lasts outside the body

¨HPV is resistant to heat and drying, and is able to survive on inanimate objects, such as clothing and laboratory equipment, that have come into contact with infected patients. The precise survival time is unknown, however. HPV has been shown to retain infectivity even after dehydration for 7 days (Roden et al., 1997).Sep 29, 2016¨

3 references showing that bleach or other level 3 disinfectants will do the job.

” It is resistant to drying and heat and able to survive on clothing and laboratory equipment although exact survival time is unknown. HPV is susceptible to a variety of disinfectants including “… 90% ethanol for at least 1 minute, 2% glutaraldehyde, 30% Savlon [chlorhexidine gluconate and cetrimide], and/or 1% sodium hypochlorite can disinfect the pathogen….”


¨ A follow up study showed that high concentration sonicated hydrogen peroxide was an effective disinfection to deactivate HPV on ultrasound probes



“Unless bleach or autoclaving is used in the hospital setting, human papillomavirus is not being killed,” said Craig Meyers.

“Trichomoniasis is the most common non-viral sexually transmitted disease (STD) in the world. Most people call the condition trich. Its name comes from the parasite Trichomonas vaginalis that causes the disease.” Quote from source:

Trichomoniasis ( Trich )


Trichomoniasis parasites are very sensitive to drying, but can survive for several hours in various body fluids or on moist objects such as sponges or towels. Source:

Symptoms can come and go, but without treatment. The infection can last for months or even years according to Once you’re infected, you can give trich to someone else through intercourse, anal or oral sex and even genital touching (skin-to-skin contact without ejaculation).

¨In rare cases, it may also be possible to get trich from contact with personal items, such as a wet towel, that a person with trich has just used. The trich parasite cannot live on objects for long, so it isn’t usually spread this way.¨



In rare cases, it can go away on it’s own but this isn’t ‘normal’ so it’s best to get it treated.

It’s usually treated quickly and easily with specific antibiotics that can kill the parasite off. NHS UK has a good article on it here.


What are the risks when sharing a sex toy during a sex session?

Of course, if you´re taking a sex toy straight of one body and putting it into another within minutes then YES, there´s a risk, if one of you has an infection, that it can be passed on. If you´re going to share toys, or have more than one partner, you know there are going to be associated risks ! The safest thing to do is cover it in a fresh condom every time you use it.

¨If sex toys are used with new, clean condoms for each partner, or are properly cleaned (i.e., disinfected) before use by the uninfected partner, they pose a negligible risk of transmission. Note that using the same condom with both partners is effectively the same as not using one at all.¨


however, conditions have to be right

¨Just because living pathogens can be found on surfaces does not necessarily mean that fomite transmission to humans can take place. The risk of fomite transmission varies depending on a number of factors. These include:
• the bacteria or virus involved
• how much bacteria/virus someone needs to be exposed to in order to become infectious
• the temperature and humidity of the room
• whether the surface is porous or non-porous
Other factors may also be involved. ¨


What are the risks when you want to borrow a sex toy from a friend?

Remember, time can be on your side here too. And, they´re also probably handing it to you in-person, so don´t be embarrassed to ask when it was last used, and if it´s been cleaned or sterilized. How about just cleaning it yourself when you get it anyway, and suggest to your friend that you would like to disinfect it properly, or sterilize it before you give it back, as a thank-you, or out of common courtesy. It´s their toy and they will have the manufacturer´s instructions so ask them how would they prefer you to do it.

We all need to get in the way of thinking like this. One of the better aspects of Covid-19, I suppose, has been that cleansing and sterilizing has become second nature to us.

Again, if you´re too shy to discuss this with your friend, then the safest thing to do here is to cover it in a fresh condom before you use it.

Be grown up, know your partners, clean a toy before you use it, or use a condom to avoid spreading germs, or getting pregnant even, in the heat of the moment. 

There is no “heat of the moment” when a seller lists a toy on Squeaky Clean Toys.

If you buy a second-hand toy from Squeaky, we ask the embarrassing questions for you 😉

Our sellers have to answer questions about the condition of the toy, and show how it has been cleaned.

It´s a serious, transactional, non-sexual business.
