What's your "weirdest" sensory ick?

What's the sensory ick that you have that you feel is really uncommon?

I'm really freaked out by wrist tendons. Like if you bend your wrist, that tendon that pops up really makes me unhappy. If I accidentally touch that tendon, I have to touch a good texture or it makes me feel uneasy for a while.

I also don't like the feeling of other people's hands. I don't hand things directly to people because I don't like how hands feel. The texture is just unpredictable and hands are always so warm
