6. Apologize to the people around you: “Sorry for the PDA.”
“Over the top PDAs [public displays of affection] can make other people uncomfortable. You could take the initiative and apologize.” This will alert your boyfriend to the fact that it’s not just the two of you, and that you may be making others uneasy. If you’re in a family environment, telling him, “There are children around!” will probably stop him in his tracks.
