Would You Mind If Your Boyfriend Responded to Other Men's Interest in You With Extra Affection Instead of Confrontation?

I wanted to ask this, If you’ve ever been in a situation where men around you, your boyfriend’s own friends, even, keep hitting on you despite knowing you’re taken, and instead of confronting them, your boyfriend just becomes more affectionate, proactive, and touchy in public settings, would that bother you?

And if it doesn’t, do you ever struggle with differentiating between when his gestures are genuine and when they’re just for show?

For example, imagine you're in a beach setting with a group of friends. Your boyfriend can’t stop staring at you, completely ignoring everything else around him. People start teasing you both, calling you a lucky couple, and while you feel the butterflies and enjoy the attention, a small part of you wonders, is this for me, or is it for them?

Would this be something that crosses your mind, or is it just overthinking? How do you process such situations?
