I only like hugging my dcs and dh. Also my mum when she was alive.
Dbro loves hugging and would hug pretty much anyone. I hate it and feel like a rabbit I a trap if someone hugs me. Weirdly, kissing hello, I'm fine with as no strong embrace.
It's taken me years to admit this out loud BTW as I know I sound like a cold fish. I don't have any trauma around hugging and as I say I'd kiss anyone (reasonably clean) hello, happily
YABU: hugging is great
YANBU: I don't like it either
