Re: changing taste question
You are what you eat. Apples are supposed to be the best food to improving taste. Also, other fruits like pineapples are supposed to be good. Asparagus is supposed to be the worst, with dairy in close second, and garlic, onions, red meat, broccoli, cauliflower, brussel sprouts, greasy food, spices, coffee, and chocolate are also supposed to be bad. Smoking, drinking, and drugs are of no help.
Additionally, her taste buds are mostly on the tip of her tongue, so if you are deeper in her mouth, she will be less likely to have a problem with the taste.
