I don’t have the wife complication but if I did and became paranoid about the lotion I would ask the provider to do the body massage without it until the grand finale. A little cleanup on the table, on the way home, or even during a quick trip to the bathroom at home immediately upon arrival should suffice. There is a bigger tattletale for wives’ ears than lotion though. Body language can scream. Stress can change voices. Don’t put your wife through that. Google relaxation techniques, use your smart watch’s breathing app, or play your most effective calming music on the way home if that works for you. Walk through the door with a tiny half trace of a smile, make good eye contact and sincerely be glad to be home.
