Transmission Via Oral Sex

[jfc77]

Last night I made a terrible mistake and received unprotected oral sex from an exotic dancer.  The exposure lasted about 5 minutes total although I was not in her mouth for the entire 5 minutes.  I did ejaculate in her mouth however.

I know there is a slight risk for transmitting diseases via oral to genital contact however I am wondering what my chances of contracting something are specific to this exposure?  Also what am I at risk of contracting specifically?  The more information you can provide the better, I'm a nervous wreck.

Thanks,

Vance is correct (Thanks).  The two statements are unrelated.

1.  No study of persons at risk for pharyngeal gonorrhea has found more than 8% of person to have the infection

2.  Most sexual exposures to persons who have an STD do not lead to infection.  

there are no data on NGU.

I suspect it is safe to resume sex with your regaular partner.  EWH

I think, but Dr. Hook can say for sure, it is of all gonorrhea cases no more then 8% are of pharyngeal gonorrhea.

NGU as Dr. Hook said is bacteria that is in the mouth and you could actually get NGU from your regular partner.

In regards to this statement also -


Does this mean that if a person had pharyngeal gonorrhea there would be an 8% chance of passing the infection to someones genitals?

Is that NGU as well.  Apologies for the additional posting

Thank for the reply, it has put my mind at ease.  

I'm not certain I understand exactly what you mean by this statement however -

the prevalence of pharyngeal gonorrhea in persons performing oral sex is no higher than 8% and most exposures to infected persons do not lead to infection.

Does this mean that if a person had pharyngeal gonorrhea there would be an 8% chance of passing the infection to someones genitals?

Also would you assume it is safe to resume intercourse with my regular partner?

Thank you again for your response.

Welcome back to the Forum.  I can see from your interactions on the STD Community Forum that you are already informed on this topic.  Thus part of my response will be repetitive.

Your statement that your risk for STD from the exposure you describe is quite low.  To repeat a statement frequently made on this site, oral sex is an inefficient way to transmit STDs.  Of the bacterial STDs only gonorrhea and nongonococcal urethritis (NGU) are transmitted through oral sex; chlamydia is not and without an obvious sore or lesion on your partner’s mouth, the chances of syphilis and herpes is likewise tiny.   If you had gotten gonorrhea or NGU you would have most likely developed symptoms of urethritis (penile infection).  Even if your partner had an STD (any STD and it is likely she did not), most exposures do not lead to infection.   To provide further context for this answer, the prevalence of pharyngeal gonorrhea in persons performing oral sex is no higher than 8% and most exposures to infected persons do not lead to infection.  

As for NGU, NGU following receipt of oral sex seems to be due to what would otherwise be considered normal mouth bacteria entering the penis.  

To answer your question about percentages, the chances of chlamydia are zero.  Estimates of your risk for gonorrhea is less than 1%.  For syphilis and herpes, even lower.

You have little reason to be anxious.  I hope my comments are helpful to you along these lines.  EWH

Also, I was wondering what the probability of transmission of an STD is assuming she is infected.  I know that my risks are NGU, Herpes and Chlamydia with NGU being the most common.  With that said is the chance something like 10% or 1 in 100, 50, 10?

I'm apprehensive about resuming sex with my regular partner at this point due to this mistake.

Thanks,
