Disappointed ....

My boyfriend and I don't really make each other horny anymore. When we first got together, you couldn't give us ten minutes alone in a dark room without my panties becoming soaking wet and his penis being on rock hard. We had to spend some time apart due to family issues, and we were seperated for a year. We've been together for 13 months now, and we just recently were reunited. I was hoping for that same sexual spark between us, times ten since we'd ben away from each other. However, it just isn't there. We can still peak each other's intrest, but the days of puddles and poles seem to be behind us. What are we supposed to do, ?
