You didn’t include non sexual intimate connection on your list at all, and that’s what I go to. My husband likes gentle touch, in a non sexual but still intimate fashion, throughout the day. It shows desire and attention for him, hold his hand, rub his shoulder when walking by, I make him laugh as often as I can, smile at him every time he looks at me, make sure we have small moments of just us being close in a hug, or a cuddle. Honestly, it’s an approach I start at the beginning of the day and maintain all day, I include a thoughtful text about how I appreciate and respect him, if I’m working during the daytime. My husband requires emotional maintenance just like I do. The trick is to make it feel “brand new” like in the beginning, so flirting goes a long way for us.
