I recently had sex with my boyfriend, without condom, I had some discharge, went to a lab, and found no infection, prior to that, the same thing happened again, and I had a UTI, now I am on an anti-botic, and taking a cream also for it, inserting it every night in my vaginal area. The discharge smelled very aciditic, and now my vaginal area is fine after taking the anti-botic. But now, between my buttocks, I have a smilar smell, like vinegar. Their is a history of diabetes in my family, can that be related?
