What kind of affectionate words do guys like to hear? (Just Misters, Please)?

Nothing dirty, fellas. We're not quite like that. My boyfriend and I are a chatty couple and spend lots of time talking and and kissing, affirmative on the coddling. So what kind of words do guys like to hear about themselves? He's actually kinda insecure so words that boost him a bit. Anyway, just some male appointed compliments, please fellas. :) Thanks
