Answering as a severly sight impaired but not fully blind person. But yes - of course! I'd throw it back at you - do you experience sexual attraction purely by looks alone? I seriously doubt it (and would be concerned if you did!). How a person sounds, smells, feels, behaves etc. all come into it. If your partner playfully blindfolds you, you wouldn't suddenly stop enjoying the experience.

Sure. And I think it's based on a bunch of factors coming together, voice being one of them. I don't know how it works if you have sight left, but I can't imagine that attraction is the same for everyone there as well. It's probably a lot more nuanced than that.
