[Question #9699] Oral Sex risk
30 months ago
|
What is a the risk of contracting a commonly transmitted STI through receiving oral sex in a one time encounter? The primary concern is chlamydia. Encounter was with someone other than my partner. Heterosexual encounter. I am male and the encounter was approximately 6 weeks ago. My current partner experiencing some vaginal bleeding during intercourse though I’ve had no symptoms at all. Would her symptoms have shown more quickly than approximately 5-6 weeks later? Thank you.

Welcome to our form. Thanks for your question. I’ll be glad to comment. Receipt of oral sex is a relatively inefficient means of acquiring an STI. When considering this fact plus the fact that most people do not have STI’s and that most single exposures to infected persons do not result in an infection, the likelihood you were infected is quite low.
You are correct that vaginal bleeding during intercourse can be a sign of an STI and women. There are many other potential causes as well. You can eliminate the possibility that your partner has an STI is the result of your encounter described above my getting tested.
---The STI most commonly acquired through receipt of oral sex is gonorrhea, which is symptomatic in more than 90% of infected persons. Chlamydia is far less common as a result of receiving oral sex. Both infections however, can be acquired through oral sex and can be asymptomatic. My guess is that you did not acquire infection from the encounter you describe, but you can resolve any concerns you have might have entirely by getting tested. A test of the initial portion of urination will provide very, very accurate results. Confidential testing is widely available and test. Results would be available after just a few days.
I hope this information is helpful to you. EWH

Thank you for the reply Dr. Hook. In reading some of the past questions/answers in the forum, Dr. Hans field has indicated the risk of contracting chlamydia from unprotected oral sex is almost zero. Do you disagree with this assessment? I realize the only way to be absolutely certain is through testing but was hoping you could expand upon risk. Thank you.

Dr. Handsfield and I have different verbal styles but we always agree on the facts. I indicated that your risk of being infected with chlamydia is quite low and told you why. Chlamydia is acquired through receipt of oral sex but it is rare. I indicated that testing would resolve any doubt. EWH ---
