Do the people have to be having sex or can a custodial child who works for the federal government use the benefits for his ailing mother? How about two brothers who share an apartment?
Also, I can just imagine the termoil in the personnel offices.....everytime a gay man/woman has a weekend affair, the one working for the Fed will go there Monday morning and change his/her "dependents" name. Then, pick up someone else next week and promise them coverage....back to personnel for another dependents' name change.

NEW pickup line: "Come home with me baby and I'll smother you in health insurance."
