19. Change It Up.
Doing the same thing over and over is boring, period. There’s good reason to switch things up: Novelty increases levels of the neurotransmitter dopamine, associated with pleasure and reward, and helps energize and focus you. That playfulness can only come when you try things in a new way, whether that’s doing something different together, taking a class, going somewhere new, anything that you haven’t done together before. It’s also worth switching things up in the bedroom too, which may mean having sex somewhere else altogether! Switch location, even shift the timing so that it feels new. Bottom line: Have fun.
