My girlfriend pointed out that we don't have pet names for each other. Now, we've only been dating for 3 months, and we've only been "official and monogamous" (her housemate's words) for 2 months, and she's still getting used to the "boyfriend/girlfriend" nomenclature, after being a very independent operator for years.

"Ham slice" is probably a non starter.
I doubt that "Oyster plate" would have legs, either.
What's your time line for pet names? BF/GF? Monogamy?
Are the time lines linked or independent?
As a rule, I don't use pet names. I have a couple of diminutives I use to show affection to people I'm close to-- Sweet Child and Kiddo, and occasionally Kid or Sweetheart. I use these with her, and with my best friends (male and female), and with my younger brother, and sometimes my pre-teen and teenage cousins.
Do you have favorite pet names? Are they unique, or do you re-use them with new lovers/partners/fuckbuds?
And do you have any suggestions?

Maybe Tulip? And Dumpling?
