most of the time the two of you cuddle on the couch, so your legs would be tangled and your head would be resting on his chest, your fingers would be intertwined and he would occasionally play with your hair.
you would cuddle facing each other. as strange as it sounds, your arms would be wrapped around him and your head will be in his chest. his head will be on top of yours and his arms would be around your waist, holding you close to him.
the two of you will be sprawled across her couch, her head would be in your lap and you played with her hair, giving her random kisses by surprise, which she loved, and she's sometimes hold your hand.
when cuddling, the two of you normally spooned. he'd have his arms wrapped around and your legs would be interlocked, his head fitting in the crook of your neck, and he'd kiss you softly on the cheek.
the two of you would spoon. when he came back from a stressful day at work, (which is most days) you'd be the big spoon, slowly running your hand through his hair as he held onto your other hand
when you guys cuddle, it's pretty simple. the two of you would lay next to each other, your hands interlocked, your head resting in the crook of his neck so he could give you small forehead kisses.
the two of you would be laying on her couch, her head resting on your stomach as you plaited or played with her hair to relax her. occasionally you'd make her jump by ducking down and kissing her, similarly to Eden.
