I visited a domme several days ago. Clearly, this activity is sexual in nature but the lady strictly advertised zero sexual contact or services as available in her sessions; only consensual BDSM play. I was surprised then, when towards the end of the session, a small wand style vibrator was produced and rubbed against my penis until I ejaculated. 

At the time, I paid this no mind, but several hours later, the implication of this additional act slowly dawned on me. The wand vibrator used on me was not covered with a condom. I had checked with the domme and she advised me that toys are always cleaned after every customer, by using hibiscrub (I believe a UK market antiseptic wash) and medical grade alcohol. But, as I'm sure you've seen many a time with posters on your forum; the nagging possibility that the toy had not been cleaned remains in my mind. I was the first "customer" that day, so if the vibrator had been used previously and not cleaned, then realistically it could have been last used some time the night before. 

Now, I must mention at this point that I have read many replies here to other questions, as well as researched elsewhere online, and I am getting conflicting information. There are worrying studies (or perhaps individual study, parrotted many times by different outlets) stated that HPV in particular can remain on sex toys, even after cleaning, for long periods of time. 

Am I right in understanding that I am at ZERO risk of transmission of ANY sti/std from this encounter? 

I'd appreciate your input on this situation. Thank you in advance! 

I would add that I appreciate your coming to our site and would urge you in the future to stay off the Internet. Many of the non-professional, so-called expert sites found on the Internet are not staffed by medical professionals and make statements which are often incorrect for a variety of reasons. Some incorrect answers come from information that is misinterpreted, that is out of date, that is taken out of context, or simply reflects passing on urban myths, which are found all too frequently on the Internet. 

I hope this information is helpful to you. As I said, I see no reason for concern and no need for testing. If any part of this response is unclear, please feel free to use. You’re up to two follow ups for clarification. Take care. EWH.

Anyway, that’s not really important to the matter at hand - that being the follow up question, which is more specifically about HPV. Can I ask what it is you think of studies such as this:

https://pmc.ncbi.nlm.nih.gov/articles/PMC6678034/Human papillomavirus DNA detected in fingertip, oral and bathroom samples from unvaccinated adolescent girls in Tanzania - PMC

I mention it because it is one of the few seemingly actually reputable sources suggesting that it *is* possible to spread HPV via fingers / objects. 

I’d be keen to know what you think of studies such as this which fly against the (admittedly more comforting) advice that HPV is almost always transmitted by direct sexual contact only. 

As always, thanks for your time and expertise. 

The topic of HPV spread through auto inoculation or transfer of infection on fingers on fingers or inanimate objects has been repeatedly discussed.  The presence of small amounts of virus is only a portion of what’s needed for transmission.  Transmission of the virus to cause infection requires the virus in sufficient quantities to start the infection, friction to introduce the virus into the skin surface and a susceptible ( unvaccinated) host.  While theoretically possible and possibly the origin of a small fraction of infections vast experience has shown that non-sexual transmission is extraordinarily rare.  EWH

In regards to the initial query of the sex toy, I would finish up my three responses by also asking: if any tingling or burning sensation is experienced in or around the genital area, especially that seems to come and go with focus on the subject or the thought at hand, would you see any reason for testing or would - based in the information in the original query - you perhaps chalk this up to something anxiety-induced? 

As this is the final reply I have I will wrap up by extending once more my thanks to yourself and your fellow colleagues for the support that you provide with this service. Truly, it is a valuable resource in a sea of contradictory information. Thank you for your time and expertise. 

Regarding the tingling/burning sensations you are experiencing I am confident that they are not associated with an STI acquired during your recent encounter.  When they cause symptoms, the symptoms are continuous not intermittent and are associated with observable signs of infection.  We find that often when clients are looking for symptoms there is a tendency to notice normal sensations which are normally overlooked.  

As you know, this response completes this thread.  I hope the information I’ve provided will help you to move forward without concern.  Take care.  EWH
