romantic or dance. It's up to you, think of the way you'd want to listen to it.
Talk about anything easy, don't discuss your everyday troubles, talk about music, books, your friends or colleagues, or just remember your college days. Even after the years of marriage you still can learn much about each other.

And, of course, make love. But do it slowly, don't rush into intercourse, take your time and enjoy kissing and caressing. You may be amazed how sweet it can be to just kiss and hug.
It's your night, include what you want. And don't forget about dating nights because of time or budget constraints. Let your house be always full of romance and your relations will be long and happy.
