mine loves to rub his nose against mine, it's delightful. when I first found him (or rather, he found us and I managed to prevent him escaping), being cuddled up to my face was the first time he purred - actually, I'd gotten frustrated that he was staying so hostile even after hours of careful enticement, and I grabbed him very much against his will, but as soon as i held him up against my face/chest he was just a little ball of purring joy.

even half a year later, when he's feeling snuggly he will get right up on my chest and try to occupy the same space my head does.
