You should know first that you are wonderful as you are. Even if you aren't his exact type (which I've been told by exes before, it can sting), you have to believe you're beautiful. Insofar as sparking his interest, have you considered maybe getting some sexy pics taken and leaving them randomly for him to find (My boyfriend's cousin is a professional photographer and basically takes risque PG-13 pics)? Men are visual and if he sees you dressed up in sexually lingere in a photo where you're feeling confident and sexy, this may help him to remember that and hopefully ambush you when he gets home.
