Romantic Nicknames / Pet Names:
Boyfriend / Husband Nicknames (A-F):
I call my boyfriend "sir" a lot, not to imply obedience; more in a cute, polite kind of way. Likewise, I'm ma'am. I don't address him like this all the time, just in more casual conversation "Hello, sir," etc.
"I love you, sir" sounds weird. =P
