You can also get thrush, creamy white patches in the mouth and on the tongue
But, a yeast infection
isnt an STI it's just an overgrowth of yeast
. We all have it in our bodies (men and women alike) and it may depend on how your health is at the time, i.e if you consume alot of sweets, a diabetic, oral hygeine. Just to be on the safe side of things, avoid oral sex when she is experiencing an overgrowth...hopefully the woman is honest when she is experiencing an unbalance.
