Do you like to eat? Or do it out of a sense of duty?
In other words, I have the same 5 basic tongue tastes that you do e.g. salt, sweet, bitter, sour and "umami". Flavor is usually taste + smell and that's the part I'm missing.
If you are more interested, I wrote a Twitter thread about all of this here: https://x.com/alexpotato/status/1559865770515087360
