Thank you so much for the service you offer.

A month ago I received a Thai massage, and unprotected oral. I have had no symptoms since this encounter, however   I recently had sex with my regular partner after a 6 month period of abstinence. She is now having a burning sensation in her vagina. Is it likely I have caught something and passed it on to her?

Thanks for your help 

The exposure you describe was low risk. Most commercial sex workers do not have STIs and even in the unlikely situation that your casual partner was infected, most single exposures do not lead to infection.  Receipt of a massage, even when there is body-to-body contact is a no risk event is terms of virtually all STIs.  Similarly, among penetrative sexual activities, receipt of oral sex is a far lower risk event that penetrative penile-vaginal or penile-rectal contact.  There is no known risk of HIV from receipt of oral sex and the major STIs when occur from receipt of oral sex are gonorrhea and non-gonococcal urethritis, both of which typically would have causes symptoms in you long before this time.  

It is far more likely that if your regular partner has not had sex in the past 6 months, she is reacting to having not had sex recently, perhaps a lack of lubrication and/or a modest disruption of the bacterial normally present in the vagina.  

It is unlikely that you have given your partner an STI.  If you are worried you can test with a urine test for gonorrhea and chlamydia (which, although rare, are the most common infections in this situation).  I am confident that the test will show no infection.  The only reason I even suggest testing is not that I think you have an infection but because many clients find negative test results helpful in addressing anxiety in these situations.  

Finally a few "don'ts".

1.  Please stay off Google- it is alarmist and frequently misleading

2.  Do not take antibiotics which will just confuse things/  

I hope this information is helpful.  If anything is unclear or there are further questions, please use your up to two follow-ups for clarification.  

What symptoms should I look out for if any?

Thanks again 

My wife was diagnosed with vaginal thrush as the cause, confirmed by lab testing. It’s proving difficult to treat as it’s still persisting after 3 doses of fluconazole. Is it likely the thrush is being g caused by a STI?

Thanks again for you advice 

This completes this thread.  There should be no need to return with further questions.  EWH
