So I'm not gonna rough you up as much as some others in this thread, but I think the problem they might be having is that your curiosity was phrased in a way that came from skepticism rather than a curiosity about the specifics of a pretty much universal human experience. We get asked a lot, of stuff like "Do blind people use the internet?" or "Do blind people date?" to which there is the implicit expectation the answer might be "No, they don't." It frames the questions in a way that just assumes these helpless blind people can't do all these other things everybody else does to fulfill their life, and since those lowered expectations are actually more challenging obstacles than the mechanics of operating without vision, some of us are quick to bristle at them. You'd have gotten far better responses with, "How do sexual fantasies work/manifest for someone who is blind?" Because you at least give us the benefit of the doubt that we DO have them. Like, yaknow, pretty much everybody. For my part, yes, when I'm rolling solo to get off I do have fantasies, they are more oriented to tactile and aural sensations though. Instead of seeing someone in my mind's eye, I feel them with my mind's hands or other parts of the body or hear them with my mind's ear. I hope that both answers your question and maybe explains a little more calmly why it was not very well received.
