For me, I often can’t be physically attracted to someone until I know and like them as a person. It makes online dating worthless, and porn largely useless. Fortunately, I don’t personally feel the lack; I enjoy it when it’s there, but don’t feel any need to seek it out. But if I did feel I need it, I can certainly empathize with how easy it would be to feel starved for affection. There’s also a lot of character-driven adult science fiction/fantasy these days (especially in LitRPG, fanfiction, and Progression Fantasy), for those times when I just do feel the need. Some characterization goes a long way.
There is an online dating app called goodnight for IOS that’s focused around voice and audio-based dating, without visuals. I’ve heard it’s accessible with work-arounds, though I don’t have direct experience with it myself. Even if you don’t find a partner there, maybe just a bit of flirting and getting used to what real people sound like when they’re trying to be attractive might be a good reset for you. Also, listen to interviews of voice actresses. They don’t sound anything like they do when they’re performing. Spending time on websites like Behind The Voice Actors helped me come to terms with how little you can really tell about someone based on voice. As someone born blind, I was way over-estimating how much information (race, physical/body type, personality, etc) I was actually getting from a voice.
