It's a pretty huggy culture with my friends! I'm not naturally affectionate so I tend not to initiate it. We all do kiss on the cheek and a hug. It really does not upset me to see my DH hug another female, and I think it's cute when the guys hug!
My best girl friends (only three) will give a peck on the lips. But I guess I wouldn't do this with a male and wouldn't be pleased to see DH do this
