John: When he calls you "My Little girl" or "Sweet Cheeks." Which usually he does to mess with you, but you love it anyways.
Paul: When he talks against your lips before kissing you. He's always smiling before he does, which make you smile as he kisses you over and and over.
George: When he touches your thigh, or hips. It always makes you blush and feel hot all over. It's probably the best feeling in the world.
Ringo: When he sings.
Ringo doesn't get a lot of recognition for his singing. And when he sings, you absolutely love it. It makes you want to scream.
