What to do after prom with my boyfriend...?

I'm a senior this year, but my boyfriend graduated a couple years ago. The problem is, he can't go to prom with me because he's too old. Knowing that i really want to go, he encouraged me to go by myself. So, i got my dress and my ticket and everything and i'm going to go with a group of friends, which should be really fun. To make up for not being able to go, i'm going to spend the night at my boyfriend's apartment after prom. I need some romantic ideas to make the night special. I was thinking incense, candles, champagne, frilly lingerie, and he mentioned chocolate-covered strawberries. Note: We just want to stay in... So no restaurants or bowling or anything. What do you think? Can you think of anything else that would make this night special for us? Thanks!
