Daily? Or on a special day? As a lady, I'd say: listen to her, really listen, be interested in the things she likes, share emotion with her. Gals bond hugely over that stuff. Also, most importantly, love her unconditionally. Always compliment her beauty, especially when she's not done-up, but be sincere. Date her. Respect her. Be considerate, polite. Praise her in front of others.
Give her a back rub or a back tickel. I know that sounds so 3rd grade. But if my man randomly just started rubbing my back or tickeling it, it would make me weak at the knees. Just knowing he WANTS to make me feel good. It's the little things like that that count the most
