Romantic Valentine's Day at Home?

I've been dating my boyfriend for about a year and a half, and he's a real sucker for sentimentality. He absolutely loves doing things for Valentines, but this year neither of us have the money to go out to eat at an expensive restaurant, so we were thinking of doing something at home. We already plan on getting lots of chocolate and a candle lit dinner, what else can I do to make the evening special?

(And please, no sexual suggestions please).
