juices taste change

Michelle

So I'm getting concerned I have a high sex drive and absolutely love oral sex. I have now hit the ripe age of 47 but people say I look late 30's (yay me). However I know that I used to taste nice like a slight sweetness but still a little sour. Now though I taste bitter and worried that will be the end of oral sex for me. Is this normal when you hit a certain age?
