Pussy juice, just like everything the body secretes, or excretes, gets its characteristics (taste, smell, color, etc.). from what we put into our bodies. Consumption of alcohol, coffee, water, vitamins, medications, cigarettes, the food we eat, and probably our general fitness all will affect how pussy juice and semen taste, smell, as well as the quantities of each that we produce.
Coffee, soda, cigarettes, some foods, vitamins,and most medications will give you a bitter taste, guys too. Additionally, coffee will also give your juices a coffee smell if you drink enough of it.
drinking plenty of water, aside from being a good idea from a healthy point of view, will dilute a lot of the other things in your body and make the smell and bitterness less noticeable. so if you need your coffee and cigarettes, you feel better on your vitamins, or you need those prescriptions to...live.
certain foods can actually make you taste better. Bananas and pineapple juice come to mind. I've also been told, although I can't confirm it, and have no desire to prove it, that people who have a mostly vegetarian diet taste much better that people who get lots of meat in their diet.
One final thought on the taste of a woman. Women who go a long time without having a good orgasm also get a musky taste and smell. This is not a bad thing, it just happens, I hapen to like it, and it stops right away after getting off.
I hope this helps.
