I'm not a game developer or even that smart so feel free to disregard my idiotic ideas, but the best compromise I can think of is to make two difficulty settings, normal mode for the masochists and easy mode for us casual shitters, I personally think that would satisfy a lot of people.
I understand you probably wanted to make it a little challenging but there is a clear difference between a little challenging and physically impossible, because even when I hit the key with perfect timing her orgasm bar drops faster than my dad leaving to get milk.
