to ask if my MIL kissing my DH on the lips is weird?

[MenaMecca]

Just a peck, of course.

During my last birthday, my DH kissed me on the lips (peck) and then my MIL saw it and asked for a kiss (same peck on the lips) herself right after.

AIBU to find it weird?

AIBU if I ask my DH not to do it again? At least not in front of me?

I once kissed my mil on lips. Went for cheek but we both misjudged. Was so awkward we didn’t say anything! Nothing! My DH found it hilarious when I told him!

Oh! Our family is a lip kissing family. I still kiss my mum and even my Nanny on the lips. Never occurred to me that it is odd and could make someone else uncomfortable
