DH and myself are in a group of friends who meet up often and there are the old hugs and kisses. This female friend of mine, who is single, always kisses my DH on the lips, and occasionally does the same to me. I don't much like being kissed on the lips and DH is not all that keen. They spend time together in the group, as I do with others, its a mixed group and no one is worried about who their partner is talking to, its all very relaxed. Is this kissing thing weird?
