Water is boring because it has no taste, but with practice you can appreciate the unique pleasure only a single oxygen and a pair of hydrogen can provide.
Most water has minerals, flouride etc especially from the tap.
The only way that water would be completely tasteless is if it was always run through a reverse osmosis filter.
This is why most water conducts electricity but if you had pure water it wouldn't because it wouldn't contain the necessary minerals to carry the electric current.
This is true, but that still wouldn't explain why you think it tastes bad. My guess is that you never had good tasting water, which for the most part, just stays out of your way when drinking it.
Yeah, it isn't. It's full of minerals and other things. It's a common experience for autistic people/creatures, some don't taste anything or love the taste but some of us hate the taste.
