Housing offered in exchange for sex

Via the AP:

On the widely used Web site Craigslist.org, some landlords and apartment dwellers looking for roommates are offering to accept sex in lieu of rent.

And all this time I thought the called this having a live-in boyfriend / girlfriend.

Trading housing for sex is a form of prostitution. But the police aren't kicking down doors.

Instead they're offering to "lease" the station's spare bunks.

The offering of shelter for sex is older than, well, real estate itself.

Damned right it is, it's called MARRIAGE.
