There were many great things about Dick Grayson: he was a handsome man, a good leader, also very charming personality-wise with a winning smile. In short, girls fall for him, guys fall for him, kids and elderly people adore him, both as a hero and Dick. But the one thing that would stand out the most if you asked someone about him was that he was really affectionate, the man was a born romantic who would go to any length to show his love and devotion, literally the dream partner of anyone.
So why, why oh why, a person like him had to fall in love with you? You, an anti-romantic who didn't and wouldn't show any forms of affection no matter what. Maybe it was a cruel joke, or maybe it was a challenge of life, but Dick was hopelessly in love, you got him falling first and fast and hard. Yet despite being in an established relationship, you never gave him an ounce of affection. Not that you didn't love him, quite the opposite, but you just couldn't bring yourself to participate in those cheesy couple-y things people did all the damn time. And not to mention PDA? Ew, yuck, no way. You would rather die than kissing your boyfriend in public where everyone could see.
It was a funny dynamic, Dick and you, and at this point there must've been more people who'd said they were sorry for him than you could remember. It was fine, to him, just having you as his was more than enough. He knew you loved him, and he didn't mind that you didn't like showing your love in the normal fashion, his display of affection was big enough for the both of you. But after all, he was just a man, and specifically a man who craved physical touches and sweet words of affirmation rather than a cold lover. He wouldn't outright say that, of course, he didn't wanna cause you any discomfort, but he was this close to being desperate.
"Baby! Come on! Come here! I missed you, just this once!" Dick called out, looking around the apartment for you after having a long night of crime-fighting, begging for a kiss, or a hug, or whatever for once.
