Hello,

Welcome and thanks for your confidence in the forum.---

There was no exposure before the condom was in place. Three days after having protected sex with the SW I had unprotected sex with my partner. Two days later she mentions she is experiencing dry skin on her genitals, itching and burning and just overall general discomfort. 

Thanks for the additional information. Happily, it does not change my evaluation or advice. There remains little or no chance you acquired an STI and infected your regular partner.---

Thank you doctor. I have just one more question.

Yes, this is possible. It is unlikely for any particular oral sex event, but the chance of course becomes higher the more frequently such exposures occur. Did you perform oral on your partner in the week or so before her symptoms began? If so, you should discuss this with her; if her genital irritation includes blisters or open sores, herpes is more likely. With her apparent yeast infection not clearing up as expected, she should also discuss with her doctor right away:  herpes diagnosis is more accurate, and treatment more effective, the sooner they are done.---

Oral was performed 2-2 1/2 weeks before symptoms started. They will be discussing this with their doctor tomorrow. My partners symptoms include sensitive dry raw skin, vulva irritation that is sensitive to the touch, discharge with no odor, and burning if urine touches the vulva. Test results will take a few days but in the meantime along with a possible yeast or herpes diagnosis could this be a uti or trich? Can trich be contracted if using a condom?

Your description of your partner's symptoms are most consistent with her original diagnosis, a vaginal yeast infection, and perhaps all she needs is a different treatment. However, herpes remains possible. Trichomonas and UTI both are unlikely based on this information, and condoms are highly protective against trich. It should be possible for her doctor to have a pretty good idea of what's going on just by examination, before lab test results are available. For example, if she has visible open sores that suggest herpes, she should be treated for herpes (e.g. with valacyclovir or acyclovir) without waiting for test results.---


I'll leave this open for one more report, but only to report the outcome of her reevaluation tomorrow. I won't have anything more to say until then.---

Their doctor performed an examination and said it could possibly be herpes and prescribed an anti viral. They took a swab and blood test and results will be back soon. 

If it's herpes, there probably are no implications about your sexual fidelity, having other partners, etc; it would more likely be from your own oral HSV1 infection, as we discussed above. Whether herpes or yeast, it's probably just a coincidence of timing, not from the CSW event. And as I said above, the timeline you describe doesn't fit well with new herpes from your CSW event: it is exceedingly unlikely you could have acquired new herpes (HSV2), transmitted it to your wife only 2 days later (with no symptoms yourself), and your wife then to start having symptoms only 2 days after that. I can't say it is impossible, but the chance is extremely low.
