Yeast infection? Noooooo. I've had Thrush only once and I wouldn't wish it on anyone. Fucking miserable
I just don't think food and drink should be used in sex for the whole hygene reasons and so on. Unless you've just got some on the side for snacks afterwards or something. Fruit in your fanny is just not the way to go for a healthy diet. Better to eat it with your upstairs mouth and all that
