How can I spice thing up?

So I’m just going to say this now my sex life with my boyfriend is descent, it isn’t mind blowing but decent. I’ve been with more men than he had with women so I guess he’s a little inexperienced, witch I’m okay with because I get the break him in😉 but anyway we always do the same positions, and I’m always undressing myself and undressing him, it’s like he didn’t crave me as much as he did before, I need some tips ladies!! What should I do? I don’t want to to leave him because I love him to much😭 send help...
