Issues with BV or off balance after sex with new partner

So recently I broke up with my boyfriend and he was the only one that I was having sex with. I recently had sex with another male and that sex basically upset my hooha. Thought I had a yeast infection Bc the discharge was white and had a diff smell. There was no itching . So I bought an off brand yeast infection mediciation kit Bc (they work just as damn good) and the smell did not resolve. Period time came and .. I could still smell the weird smell. I was like this is not me at all. So I went and got tested . Test was clean. And I realized it had to be BV. The same thing happened to me before when I had sex with another individual. So I'm really going crazy now trying to think of cures other than medications and boom here it is : a douche and apple cider vinegar diluted with water. Majority of doctors say douching is just not a healthy thing but I flushed myself right out and 24 hours later , my balance was back the smell was gone. It worked for me and it may work for you.
