What are some endearing (not sappy), old-fashioned nicknames I can call my boyfriend?

Hi there. I'm not really into the whole "pet name" deal but I'd like to show a little affection to my boyfriend (we have been friends for 2 months and have been dating for 1 thus far..so keep that in mind in terms of the degree of affection I'm looking for). What are some old-fashioned nicknames that are endearing but not creepy (e.g. sugar lips, baby, boo bear, etc.) for a beau?
