Canon only showed a little, but I know he gets a little flustered with women and nervous and blushes easily.
He is very caring, but he doesn't spoil or baby me. He also puts his foot down if I try anything he doesn't like or if he sees me waddling too much in self pity. He's a very warm figure, and he became very physically cuddly in time. At first being more shy and asking first if it's okay to kiss me or not, that type. Which I really like.
He takes a lot of note of affection I like and things I say to him, and doesn't forget a word of it. Which goes both ways, as I said he doesn't let me walk all over him or use him as a hug blanket. It's something I love a lot about him and has helped me a lot.
