You youngsters complain before you think.
Slow is for sleep, as it won't keep you awake with noise or sensation.
Medium is for regular daytime use. Helps to not have extra "insulation", if you know what I mean.
Fast is to keep each other from overheating during sex. Nobody likes sweat puddles in bed. Bad for traction.
