Gonorrhea and Chlamydia from blowjob

Question: 

I received blowjob from a CSW around a month ago. The blowjob act was unprotected. However, there was no cunnilingus or penetrative sex involved. I know that transmission of HIV in such a case is quite unlikely, however, I am concerned about other STIs, more specifically Gonorrhea and Chlamydia. What I know is that the symptoms for both of them usually appear approximately within 10 days of contracting the infection, for males. Since, it has been more than a month now and I have not experienced any symptoms, except for some rashes around the genital area, which I think is not a classical symptom of these STIs, I wanted to ask:

1. What are chances of contracting Gonorrhea/Chlamydia through unprotected blowjob, with no other type of sex involved?

2. Since these infections are usually treatable with antibiotics, I wanted to ask that what happens if these infections remain untreated for around 6 months or a year? Are these infections treatable a year after contracting them?

3. Considering that no other specific disease is present, can a CBC or urinalysis somehow indicate the presence of these infections?

TIA.

Answer: 

Hello,

Thank you for your inquiry. From what we gather from the question, you were asking about the possibility of acquiring HIV and other STIs after receiving a blowjob. From the information given, the HIV risk in this scenario is determined to be Negligible Risk (there are no evidence or no documented cases of transmission), but the risk of acquiring other STIs, such as chlamydia, gonorrhea, syphillis, Herpes, and/or HPV, is present.

The scenario mentioned above does not meet the three components of the Transmission Equation, although there is a theoretical risk of HIV transmission if there is a lot of HIV-containing blood present in the saliva of the person giving the blowjob. In terms of the other STIs I have found a very informative website to address your first and second questions. Please refer to the STD Risk and Oral Sex - CDC Fact Sheet for specifics about the risk of acquiring the previously listed infections through receiving oral sex. Using a condom for future sexual encounters will help to lower your risk of acquiring HIV or other various STIs.

Please note that each of the STIs has a specific test that can be conducted to detect if you have the infection. Chlamydia and Gonorrhea are often tested on a urine sample or a swab, whereas syphilis is typically tested from a blood sample and in come cases a swab.

Recommendation: There are no evidence or no documented cases of HIV transmission through receiving oral sex. Please refer to a physician for more personalized answers and to inquire about other STI testing.
