Pet Names for My Lover

I've been musing over a loverly name for my new boyfriend. Don and I call each other 'darling' except when we're angry; then we use first names. Joe calls me 'sweetheart' or by my first name, which I really like. I like using his first name, too, except that it's so short. The syllable is over before it's even begun. He likes it when I call him 'Boy' so I'll use that, plus add miscellaneous syllables to his name stretch it out and add meaning: J-boy, J-beau, J-dear, J-daddy. And the occasional 'sweetie pie' and 'sweetheart.'
