what does Mango taste like? well, like mango, right - taste is very hard to explain. It's a bit salty and a bit sour, and also very different between different people. As said, try your own to find out.
Also, spit and sweat are a good indication as to what to expect. If you ever tasted sperm it's also a good indication as to the realm of flavor you can expect though the texture is different.
