[Question #11883] Oral Sex Risk

11 months ago

Hi doctors,

I recently asked a question about oral chlamydia and oral gonorrhea.

I have returned with a couple of new questions.

The basis scenario is that, 2 years ago, I gave a man oral sex. He wore a condom and did not ejaculate.

1. What is my risk for mycplasum genital in my mouth? I gave oral sex to a woman ten months after the man. Would she be at risk of mycoplasum bacterium if I ahd it in my throat?

2. A couple of months after the oral sex, I tested negative for all hepatitis and syphillis. Are my tests conclusive?

3. If not, 2 years down the line, would my body have cleared any hepatitis?

Thanks in advance.

Welcome back to the Forum. I'm sorry you continue to worry. I'll try again to allay your concerns. In reading your new questions, I find myself wondering if youhave been searching the internet about the encounter that occurred two years ago. If so, I urge you to stop. Much of what is on the internet in incorrect and misleading and it is hard to tell what is true and what is not. Much of our efforts on this Forum are dedicated to correcting internet misinformation. Regarding your current questions:

1. What is my risk for mycplasum genital in my mouth? I gave oral sex to a woman ten months after the man. Would she be at risk of mycoplasum bacterium if I ahd it in my throat?

Mycoplasma genitalium rarely if ever infects the throat. I am not aware of any instance in which someone acquired M. genitalium from receipt of oral sex. Testing for oral M. genitalium is so rare that it is not recommended.

2. A couple of months after the oral sex, I tested negative for all hepatitis and syphillis. Are my tests conclusive?

Absolutely. A negative test more than a year after a potential exposure is conclusive.

3. If not, 2 years down the line, would my body have cleared any hepatitis?

The only form of hepatitis transmitted through heterosexual contact is hepatitis B. If you are vaccinated against hepatitis B, you are protected. Hepatitis B is not transmitted through oral sex.

I hope this additional information will help you move forward. EWH

Thanks very much for your answers. They are great.

I will just ask these two last ones:

1. So, just to confirm, even though I performed oral sex on a man (with a condom), hepatitis b is not transmitted this way?

2. I think I phrased one of my initial questions poorly; my apologies. I'll rephrase it: is a syphyllis and hepatitis test conclusive two months after giving the oral sex (with condom)? Mine were negative after 2 months, but I have seen some sources, which may be incorrect, say that these tests should be done after a 3 months or more.

Thanks very much in advance.

Straight to our follow-ups:

1. Correct

2. I suspect the sources you are referring to are on the internet. I can't tell you how much of our time we spend correcting internet misinformation. The 3 month criterion is out of date. Your exposure was virtually no risk and your 2 month tests prove that you did not acquire syphilis or hepatitis. If you need to repeat the tests, do so as I think the emotional toll you are paying for your regrets related to that encounter is substantial. I am confident the tests will be negative, Then you need to accept the results and believe you did not acquire an STI and have not transmitted it. It's long past time to move forward.

Please stay off the internet. EWH
