How can I make sex more exciting?

Besides new positions. It's weird but I don't get pleasure from most positions besides him on top with my legs up.

I have lots of lingerie. We tried eating stuff off each other which we just found sticky and awkward. We do it on the couch. The floor etc. But usually it's exactly the same. Foreplay for him. Foreplay for me. Sex. Cuddles. Which is all lovely but what can we do different to spice it up??
