Unusual loving from my dog?

my dog has always been very efectionate towards me but his funniest bahavour is and the only way i can give you a picture of it would be to say that when a child sits on your knee arms around your kneck and cuddle into your kneck now with that pic in mind what he douse is puts both pawss on your knee and snuggles right under my chin he also douse this to other women is this just a normal bahavour of a loving dog
