Once work is over, phones go down and we watch TV together. If he’s been playing XBox while I’m out of the room, he turns it off when I come in.
We always sit next to each other on the sofa (bad mum alert - even if it means moving one of the DC to the other sofa!) so that we can hold hands or stroke arms etc while watching TV. We have specific shows that we only watch when we’re together, or if we agree to watch at the same time apart.
We text when we’re apart. (We don’t live together so see each other 3 nights a week). Sending a quick cute message, sometimes just a single word which signifies that we’re remembering something nice, or a photo from one of our lovely holidays, lets me know that he’s thinking good things about me while we’re apart.
Every time he’s here we will both assume sex is on the cards. First one in bed lights the candle so the other one knows it’s on which is considered to be a ‘legally binding contract’ 
It means we keep the physical connection, as the default is ‘yes’, we opt out rather than opting in IYSWIM.
We always kiss and hug when saying hello and goodbye, good morning or good night, as well as lots of times in between. Passionate kisses in the kitchen, a quick hand up the back of his t shirt for a back tickle while we’re talking, or some sneaky fondling when nobody’s around, all help too.
I take an interest in his work, and he in mine. He’ll apologise about potentially boring me with details but I like to know what’s happening in his world and it means a lot to him that I remember the small details. On the plus side, if ever he gets the sack, I reckon I could do his job now
