How can I spice up the sex?!!

I am recently married, have been with my man for years though and have been intimate for years. I feel like we are in a rut right now in our sex life. We have sex a lot but the adventure has slowed down and it's basically the same position every time :/ does anyone have suggestions to change things up and spice it up? I also don't want to be the only one that makes the effort....thoughts? Ideas?
