Advice and suggestions, please!

My husband and I have been married for 1 year 5 months. We grew up with people making sex seem like it's bad. We both love sex, but sometimes it can be difficult for us because of those voices in our heads of those people. I'm all into the lingerie and trying new things. How do I spice up the sex life and make it happen more often? It also doesn't help that by the time we both have time to do anything we are just tired for working and end up falling asleep on the couch.
