It is hard to feel authentic holding someone’s hand, especially if you are in public. Although hand-holding is a sweet gesture, when doing it, I always feel contrived. Like I am forcing a point and trying to prove my love to the world. Holding the hand of a lover is kind of like walking around holding their penis except less potential for mess.
Holding hands with a friend also seems kind of off. I love my friends, and like being affectionate, but when you grab their hand to walk down the street you both will be hyper aware that your hands are hugging, and probably spend the entire time stressing about how to break the bond. “Am I going to pull away? But what if that hurts your feelings? And if you pull away it will definitely make me feel bad about myself, but I really just want this to stop.”
