Yup, it seems there is no solution. No matter what we say or how how we say it will probably offend someone. Even well-intentioned suggestions are misinterpreted to be "mandates" and arm twisting. Makes me smile sadly.
It is interesting to learn the origin of the phrases we use today. Here's one I like:
The word "smooch" as in "to kiss" comes from the word "smudge". When a girl wearing lipstick kisses, it sometimes leaves a little smudge of lipstick or lip rouge. So, the phrase "give me a smudge" eventually became "give me a smooch".
