Good questions to ask your girlfriend and much much more
You can choose from fruits, like strawberry or you can choose from sweets, such as cupcake. Your girlfriend will love that you see her as sweet and cute as those sweets and fruits. But make sure not to call her anything that is connected to heavy meal, like pork chop. She will definitely not see that as cute and will probably think that you see her as fat. Cute animal is another category you can choose from, such as kitty cat.
