I can only speak from personal experience. My husband, who is mostly German and Austrian, found the constant physical contact by my family off-putting at first. Gradually, he's grown to accept it as the norm, but his family is definitely NOT as touchy-feely as mine.
My husband points to our wedding as the perfect example. When I danced with my father, I clung to him, crying my eyes out. When it was my husband's turn to dance with him mom, she maintained a wide physical distance, and when he tried to say things like, "This is the only time in our lives we'll ever dance like this," she would quickly change the subject to, "You're all packed for your honeymoon, right?"
My daughters have also noticed that their paternal grandmother will rarely say the words, "I love you." My oldest will purposely say it on the phone now before hanging up, but my MIL will usually answer by blowing kisses.
