i dont think leons the hand holding in public type of guy.
there are times he does reach for your hand, of course, like if you're spooning him, he likes to put his hand on yours where you hug him across his ribs.
if he notices you're fidgeting or nervous. he squeezes your hand to remind you he's there, that he loves you.
if he notices your hands are cold, his are covering yours in an instant, rubbing warmth back into them until he's safisfied that you are no longer apparently at risk for frostbite. if you're on the move together, he's holding one of your hands in his jacket pocket. and he will switch sides to ensure both of your hands are warm, if necessary.
additionally, he's never denying you or pulling away if you reach for his hand. he will gladly thread his fingers through yours, running a thumb over your knuckles until you're ready to let go.
but these are all specific circumstances. if he's needing to feel you, which he pretty much always does, he foregoes hand holding for something more intimate to him.
his go-to is a hand on the small of your back. whether he's passing by you in the kitchen and it's a brief touch, or he's standing next to you in the store while you're explaining something to him, palm pressed firmly to that dip in your back like it was carved out just for his hand.
if you're in the car together, his hand always finds its way across the console to grip your thigh. it doesn't matter which one of you is driving, his hand is always there, tapping his fingers to the radio, giving your leg a squeeze when you say something that makes him laugh.
you decide to wear bottoms with a pocket, with belt loops? his hand is finding its way in your back pocket as you walk wherever you're going. he can't help that you happen to own every pair of jeans that fit you perfectly. if he feels like it's a little too handsy for a public situation, he hooks his thumb into one of your back belt loops, his arm resting around your waist.
if his touches are a little possessive, so be it. you lean into him every time and he loves having you underneath his hands.
