If the game is about "setting the pace" then cut the prompt bs with "clapping" sounds and glowing dicks.
You either have a game where the player sets the pace, or a prompt/cue following one. You are trying to do both which do not work.
Listen to what most people are telling you. I literally created this itch.io just so I could comment, not because I'm a hater,or hated the game, but because I saw potential in it, and was sad you work will go down the drain because of the awful sex mechanics.
I understand that as creator you have a vision that to you makes sense. But you're too close to it, to see its flaws. My suggestion, make changes to the minigame and A/B test it. See what people actually prefer and feel it fits better to the game you're trying to make.
