I wonder if this works for urine...

SAN FRANCISCO (Wireless Flash) -- Oral sex is not for every taste, but a berry-flavored smoothie can help improve the taste of oral sex. That's according to San Francisco-based "sexpert" Sadie Allison, author of a new book, "Tickle His Pickle" (TickleKitty). She recommends men chug down a smoothie made with orange juice, strawberries, bananas, blueberries and peaches at least eight hours before oral pleasure to sweeten the taste of male bodily fluid, making it less objectionable to their partner. Some foods can sour the taste of semen, so Allison suggests men avoid garlic, cauliflower, broccoli and asparagus before sex. Not all of her penis pointers are aimed at men. Allison says women should avoid excessive yanking, coarse hands and comparing their partner's privates to previous lovers. Also, she says dry mouth can be a serious setback to good oral sex so it's crucial to keep sour cherry candies nearby just in case.
