Dear Mandy: I've been having lustful thoughts...

Dear Mandy, I've had lustful thoughts about a co-worker...do I need to tell my girlfriend or just hope these feelings go away?"

Dear Conflicted, If it's just lustful thoughts, get over it or get single. Why would you tell your girlfriend? What is she going to say to you? "Uh, thanks for telling me...?" This is something you need to keep to yourself, and if you're really loyal to your girlfriend you'll shoot the feelings down. Whether that means purposefully avoiding your co-worker so you don't see her perfect childbearing hips, so be it. How would you feel if your girlfriend came up to you and said, "There's this really hot guy at work...like seriously, rippling abs. I'm attracted to him, but I still love you." NO, THANK YOU. Confessing something like that only adds unnecessary drama and insecurity to a perfectly good relationship. Keep your feelings to yourself, and take whatever measures you can to make the feelings stop. If it's more than just lustful thoughts, you might need to reevaluate your relationship with your girlfriend.
