I’ve been battling a mild YI on-and-off (mostly on) for the past few months. It would usually abate during my period and for a few days afterwards I’d be symptomless, but it always returned before ovulation and lasted throughout my cycle. I tried changing my diet, though probably still had too much sugar, and eating plain Greek yogurt with honey. I didn’t sleep with any pajamas or underwear on to air out. No luck there. I tried my best to abstain from masturbation, and went a whole month with no PIV sex with my male cis-gen partner (I’m female cis-gen, btw.)

So the other morning we were both fed up with not having sex. My symptoms, while not gone, were mild and so my partner wanted to try having sex and I was enthusiastic as well. I am not on HBC but we did not use a condom since I am about to get my period and not fertile. sex was fun (and he came inside me) but afterwards my labia were itchy and swollen, which only happens during YIs for me, typically.

However, since the sex (3 days ago) my symptoms have been abating. No itchiness, not much smell (I had the sourdough smell going on) and no discernible cheesy discharge. Do you think this is due to my body gearing up for my period, or could the semen have had an effect on my vagina’s PH? I was going to see my doctor tomorrow, but with no symptoms now, I’m not sure what I’d have to show for it.

    Yes, I believe semen is basic, and a healthy vagina is acidic, so it can throw the pH off. It’s possible that it’s just a mild yeast infection that flared up from the sex. Also, though, you might consider treating your partner for a yeast infection as well, as you two could be passing it back and forth. Males usually don’t experience symptoms so it’s hard to tell, but if you’re not using condoms it might be a good idea.

    Vaginas are very acidic but if you have a yeast infection, your pH doesn’t change. You would know this if you’ve ever done a pH test kit: if it’s basic with symptoms, it’s probably BV. Normal pH with symptoms, yeast.

    It could very well have been yeast. I always keep boric acid capsules on hand for whatever my vagina decides to do 🙂

    That’s really good to know! I’m going to see what happens symptomatically once my period is over; if things return, then I’ll follow up with a doc. I’m fairly sure it’s a recurring YI, but I’ve had BV once before and it wasn’t terribly symptomatic, so I would probably want to rule that out just in case.

    Also, where does one find a pH test kit?
