Spice Sex Up?

We have only been married for three years and parents for one, but I feel so bored with our sex life. I love my husband but our sex is honestly so mundane; it’s missionary, 30 minutes tops and my husband always finishes. Afterwards I feel like “meh, that was fine,” which sucks because our first year together we had such passionate sex.

How can I get that back? How can I get my husband to be less vanilla in bed?
