What happens when the "lower desire" person prefers self masterbation vs. interactions with the higher drive person. So the one always initiating gets rejected 95% of the time and the "lower desire" person waits until their partner is asleep or away to masterbate. Or the "lower desire" person tells the partner to use their devices to satisfy themselves. The "lower desire" person flirts with and physically teases the higher desire person to show interest and desire but then shuts it down the moment the higher desire person responds.
