I give my dad ice cream, though that's not seen as romantic. My sister says I eat too much ice cream. She's horrified at what I eat, and has a big stress whenever I eat or snack on something that she wouldn't eat.
I once had a terrible date where I find out he was allergic to seafood, and I love seafood. I was scared that if he ate what I ate, my date would go into shock or be at risk of dying.
I also had a date with an Indian guy who laughed at me when I ate chilli flakes that I did not know were chilli flakes.
I don't recommend spoon feeding your date, its not romantic, but some people like to be babied and love to be called 'baby'
