Ashton: Ashton was very silly about PDA. He'd randomly grab your face leaving kisses everywhere on it except on your lips in the middle of your sentence, making you giggle uncontrollably. You adored his silliness.
Calum: Calum always like to touch you. Not in a dirty way, but he liked to always have his arm around your waist, around your shoulder, or he liked to hold your hand. It pretty much became a regular thing. You noticed when he wasn't touching you in some way, and it felt weird.
Michael: Michael wasn't big on PDA. He was more laid back with relationships, and liked to keep it to himself. You didn't mind, because you were the same way. Although, you have to admit that the rare times he did show PDA, it made you fall more in love with him.
Luke: Luke was very affectionate. He liked to have an arm around your waist at all times, occasionally kissing your cheek. The fans had tons of pictures of you both kissing in public, because he was just that way. The other boys grew sick of it fast, but you guys didn't care.
