I can not really recall if my family was affectionate.. I suppose it was more of a rarity with my immediate family. My mother's family though, we are all huggers. However, I reserve contact for my close friends and family. I am okay when other people try to hug me, I just have to pick up on the cue. I will not try to hug anyone outside of my family, friends have to initiate it.
If someone tried to kiss me on the lips, honestly, it would bother me. I can not pinpoint why exactly, but it would. The kiddo hugs me sometimes and she will go to kiss me on the mouth and I automatically avert but kiss her cheek or the top of her head.
Obviously, I am most affectionate with my partner. I love to hug and hold hands and cuddle, but reserve that part of me for my partner. Sometimes when we visit my family I will cuddle up next to my mom and put my head on her shoulder, but we have not always been like that. My dad is a big hugger now that I've grown, and I like it
