I love this thread since holding arms and even being touched is a bit out of my comfort zone. Im not a touchy or cuddly person unless I really like that person.
But if a friend insist on holding or wrapping her arm around my arm, I dont fight it. I just let my arm hang down or it in my pocket. But I dont do the holding hands nor be the one that wrap my arm around hers. I know it can seem mean lol.
