I love teasing Cap privately in public (makes sense?), and if you knew him you'd know how much it kills him. He is such a non-exhibitionist and is scared to death that someone would see a bulge. Once he forgot to pack his boxer briefs when we went to the beach and he had to go commando! It was freaking hilarious! I was constantly teasing him under the table and it drove him crazy. The added benefit was that after he finally settled down in the restaurant we went to a gift shop just to browse. With all the teasing and then walking around he came to attention just spontaneously!
Poor thing, he called for me from a few aisles away. When I finally went to see what was the matter he said "I have a problem." A big problem, LOL! Poor thing, he was just begging to be teased now, but I just didn't have the heart. There were just a few other people in the store since it was kinda late, but I kept telling him "watch out, that little girl is coming this way." He would freak! I finally had pity and walked in front of him with his hand on my hip while we walked out the door.
But I would never tease him to show him off to others. That just sounds weird to me.
