I generally don't think about sex unless it's relevant to a discussion so the analogy kind of breaks down for me. But when you liken something to food, the immediate thought coming to my mind is that you can't live without it.
I guess if you really wanted to stick with the food metaphor from my perspective it would be more like: "If all food tasted bland to you and you didn't have to care about the nutrients/hunger would you still eat?" Taking the analogy past its breaking point, my experience is like that question but if the world fundamentally judges you based on your favorite food and inserts generic barely related food pictures into every show or movie you try to watch.
That's fine? I'm not trying to gatekeep being ace at all nor speak for all ace people. That just doesn't match my experience and I doubt I'm completely 100% alone in saying that.
