What are some cute flirty things to do with your boyfriend?

I have a boyfriend and were flirty a lot. We snuggle, rub noses together, kiss cheeks, hug close and hold hands. We each have little cute names for eachother and we blush easily We do little flirty things like that and i love it. Im wondering if there is any other flirty things i could do that in public, when alone, etc. I just dont want things to get stale or gets tired of the same things.
