[Question #6029] Risk Assessment to Partner and Self
19 months ago
I am a male. I had one evening of poor decisions and I would like to assess my risk to my partner and self.
At the end of January 2019 I had no more than 1 second of nude apposition and unprotected oral where the female put my penis in her mouth for a brief time of less than 2 seconds.
77 days later I had unprotected oral and vaginal sex with my partner.
2 weeks after the unprotected sex with my partner (88 days after the possible exposure) I was tested for gonorrhea, chlamydia and trich. All tests came back negative.
My questions are the following:
1. Can I take my negative tests 88 days after the possible exposure as being conclusive that I did not contract an infection from the exposure in question?
2. My partner and I did not have sex after the above mentioned episode until July ( 4 months after the last sex episode). About a day after having sex she unexpectedly got her period (about a week earlier than usual). It seems as though her cycle was reset as her period came around the same time in August as it did in July. We recently had sex and her period came the next day and lasted 6 days. This was two weeks after her last period. The change is concerning to me and makes me wonder if I were to have infected her given the change in her cycles and the possible relation to having sex. Prior to the July episode she experienced no concerning symptoms and had normal cycles.
Any insight you can provide is appreciated.

Welcome to our Forum. Thanks as well for your confidence in our service. I'll do my best to help. The encounter you describe was very low risk. There is no risk for any STI from the apposition you describe and the risk from receipt of oral sex is very low, both because it was oral sex (even in higher risk persons most people do not have STIs and oral infections are less common than genital infection) and because of the brevity of the exposure. Most people do not have STIs and even when they do, only a minority of exposures lead to infection. Further, the absence of symptoms and your recent negative tests add to the evidence that you did not get an STI from this exposure. I would not worry further and see no need for further testing.
In answer to your specific questions:
1. Yes, you can be confident you did not acquire an STI from the events you describe.
2. I would not worry about an STI causing your partner to have a change in the timing of her menstrual cycle. While some STIs can occasionally cause intra menstrual spotting, they do not change the timing of cycles.
I hope this information is helpful to you. EWH---
