Thank you for your reply. The timing of the yeast infection had me worried. I don't know if the symptoms were typical for other episodes as that isn't something she discussed with me.
I'm curious if someone had symptoms of chlamydia or gonorrhea and had no reason to believe they weren't a yeast infection, how likely would they be to mistake it for a yeast infection? Are they really similar enough that it could fool someone who had no reason to suspect an STD?
Finally, how long would spontaneous cure typically take? In other threads (e.g.
http://www.medhelp.org/posts/STDs/Chlamydia-/show/1771743) you've mentioned that chlamydia is rarely carried by men for more than a few weeks or months and that pre-antibiotic gonorrhea was believed to clear in an average of six weeks. Is the overwhelming case a few months rather than weeks? I hate to ask for clarification but I'm worried sick about my wife being harmed by one of these diseases but I obviously have a lot to lose by revealing this one time infidelity.
Also, I intend to get the HIV and syphilis test this week. Thank you again for your advice and knowledge.
