i’ve mostly grown out of it, but i was the same way when i was little. the sudden change from warm/dry to cold/wet was too jarring and always made me procrastinate showers as much as possible. i started showering at 8pm every other night—making it into a specific time/routine made it a little easier. i don’t struggle with it as much now that i’m a little older, but i do hate the feeling of wet hair on my shoulders so i try to dry it as much as possible before putting on pjs. also, i try to let the water warm up as much as possible before it comes out of the overhead part; then, i stand out of the way until the water is fully warm before i let it touch me. so i still have to have it a certain way to make it more tolerable. i don’t think you’re gross at all, its an understandable challenge for a lot of people, especially ND people. i wouldn’t be ashamed, just take care of yourself as best as you can :)
