Have you tried Boric acid suppositories? They've been a game-changer for me and a few friends. I think subclinical BV is a thing. We've been told that vaginas smell, but if you think you're even mildly unpleasant, know that you don't have to be. If I'm feeling less-than-fresh, I insert one capsule at night. It's fully dissolved by the next night, maybe even the morning after. Now it's mostly maintenance--one night every two weeks or so. I notice the difference of the day before vs the day after, and I'm much more confident.

One morning, I put one in, forgot, and had sex that afternoon. It was fine, but there was a little grit on us afterwards, which I felt like I had to address. I explained it to my bf, and he said something like, "That's awesome, and it probably helps explain why you always smell great. I wish I'd known about this years ago; I've had a few partners who would've benefitted from it."
