How could I spice up our relationship?

My boyfriend and I have been dating for about 1 year and 10 months now (almost 2 years and no, I don't count down to the day, although....I suppose I could ^_--) and he's at college most of the week. Rarely, I get to see him a few days on the weekend. I was wondering if any of you have some advice on how I could spice up our relationship a little and make him come running home?

Dirty talk on the phone!!! when you are on the phone start up some dirty talking of what you want to do to him when he gets home and tell him you'll be waiting for him ready to jump his bones! that should get him running really fast home!
