One more question i had used a lubricant from sex store that caused a cooling sensation and it had fruity smell. after i used something didn't seem right and gyn said i had bv and yeast. i thought it was from that?

Possibly: It's possible the lubricant changed the bacterial environment in your vagina enough to cause bv. Monotor for recurrence if you use the lubricant again.

Cause vs association: BV & yeast are both caused by germs. In the normal vaginal environment you have factors that suppress these germs & any foreign substance may alter the normal and allow these germs to thrive. It is not like the lubricant brought the germs, it likely just allowed them to take hold.
