Favorite ways to make your partner feel sexy?

I’m at a low in my relationship after a year and a half of being with the love of my life because of lack of sex. A lot of it is because we both live with our parents so it takes away from the time we have available. But also sex has become the least of our priorities with both of us working so much. We’ve gotten so comfortable where we are now that neither of us knows how to initiate sexual play without feeling awkward and nervous. Any tips on boosting either mine or his confidence and getting a little foreplay started?
