We all need savory, sour, spicy, and sweet. All about balance.
Quick side note. Had a cavity filled 20+ years ago and while injecting me with Novocaine the dentist severed a nerve that ended up leaving one side of my tongue completely numb for about 6 months. Sucked because I'd end up biting the **** out of it while eating and not even feel it.
Cunnilingus was a trip though.
