Does pineapple juice really make you sweeter

So, I have an sexual encounter coming up later on today, and I kinda wanna add a little razzle dazzle to my lil lady because this will be the first time he’ll be giving me oral sex. I already know she smells good because I drink plenty of water, and eat well but I just want it to taste “sweet”. I’ve always heard that drinking or eating pineapple could achieve that but I’ve never tried it myself. So before I go out and clear the shelves of all the pineapple juice. Has anyone tried it? And does it work?
