(New York Post) Forget bed bugs. There’s a new parasite moving into apartments. This one has two feet, a sex drive, and travels with a duffel bag.

The now defunct williamsboard.com called them “sex gypsies” — people who hook up largely so they have a place to stay. They’re not quite homeless, but they’d rather go to your place than theirs. And they’d like to stay for as long as possible. (And no, it’s not just a story line on “Girls”!)

Roland, a 33-year-old teacher from Bed-Stuy, claims he became a sex gypsy in 2003 when his roommate moved out and he could no longer pay the rent. He’d been couch surfing at friends’ places and spent a few nights sleeping on the L train. Then he met an attractive woman in a bar, went home with her and didn’t leave.
