2, I think there is some discrepancy there. For instance, I like to show love by giving gifts, but I don't like to receive gifts. I like words of affirmation, but I'm not very good at giving them.
By your definition, if my H's LL is physical touch and feels loved when I please him sexually, he should want to show love by pleasing me sexually. That doesn't happen.
I think we all give/need some of all of them. I am not understanding the need to label it, especially if the specific "action" need is defined.
