How do I make this EXTRA special?

Today is obviously Valentines Day, but its also my SO birthday…..

What can I do to make this evening EXTRA special for him?
I have no children tonight (they are with their dad) and the baby will be in bed. I have bought him steak, I intend to run him a bath and pour him a drink when he comes home…but I am so unsure what will make it special for him?
