I have a boyfriend of several months who I'm happy with when we are together. But once I get to work, I can't stop thinking about my co-worker. I've been sleeping with this guy at my job since I started there. However, what goes on with this guy happens only at work. I want both of them, but I'm scared of losing them both. So, I've been sleeping with them both for a couple of months now. I don't think I could stop even if I wanted to.
