Just curious really.
I am in touch with some my family but we are not huggers and things can be tense. Have no partner, and sometimes really could do with a cuddle, and sadly there is rarely anyone there who wants to cuddle me 
Realised this last week when at the dentist and was terrified, and a friend came with me for moral support. She stroked my back throughout and it really helped calm me down. I'd always hug friends anyway, and they are genuinely affectionate hugs, but this felt different. As if normally my hugs are more mutual, and this affection at the dentist was her being the one giving the support, and in that moment I wasn't giving anything back? I don't know if I am explaining accurately!
Anyway, do you get much affection and comfort from your friends in general? How common is it for you?
