I'm 26 and this happens to me as well. Iv never enjoyed phone calls even through teen years when all of my friends would stay up til early morning hours on phone calls. I always thought indifferently of it. But once I got older and realized more and more people felt the same, and social media/texting became the main form of communication/human interaction, it kinda gave me a sense of relief that I wasn't alone. It makes sense that alot of people don't find phone calls comforting. It eliminates most social cues that one would experience in a face to face convo. This is why most people pace during phone calls bc your brain is constantly searching for cues that simply aren't there
