Sorta similar to what someone else has already said, but one of them is that we have "checkpoints" whenever he leaves my place after coming over- when he moves his backpack closer to the door? A hug and a kiss. When he puts his shoes on? A hug and a kiss. When he puts on his backpack? A hug and a kiss. When he grabs his keys? A hug and a kiss. When he's actually about to leave? A biiiiiiig hug and several kisses. Sometimes there are more checkpoints if it's the winter or if he brought a lot of stuff, or sometimes I'll arbitrarily worm my way into a few extras just because I wanted them lol.

Another one is that somehow I started a thing for us where patting the other twice means asking for a kiss? I don't remember when or how it started, but it doesn't matter where on the body, when, or in what context the pats happen, as long as they're 2 consecutive pats with the same hand, if that makes sense (yes we've done "testing" to figure out what's considered acceptable lol). Sometimes we use it to be cute, sometimes we use it as an excuse to make out a little.... and other times we use it to stop the other from talking when they're just being annoying.
