A 41-year-old female asked:

Is it bad to perform fellatio before having sexual intercourse? does the saliva from oral sex lead to vaginal infections, such as yeast infections or bv?

Not particularly: Saliva has some anti-bacterial properties. Chance exposure to some germs may occur but I don't consider it much of a factor. BV is a product of having vaginal secretions rich enough in glucose & protein to support the growth of any germ that enters.
