Have sex everywhere! Couch, kitchen table, shower, car, public toilets etc.
Into being dominated? If you haven’t tried, but want to, start easy by just blindfold (you can use a scarf), tied hands (use scarf), light spanking and dirty talk.
Tease each other in public, and when you get home he will be all over you.
There’s a lot of stuff you can do to make sex interesting
