The Girl's Guide to Depravity

Lizzie and Sam see a plain woman with a handsome younger man and wonder how she holds his attention. Someone suggests she has a "magic p**sy," something no one can define. Lizzie is determined to unravel the mystery. First, she and Sam attend a tantric yoga class, but are tossed out when they start laughing. The girls are talking things over when Cheyenne, Tyler's sub at the bar, volunteers that she once had a magic p**sy -- until she had a baby. Next, the girls try a special steam treatment for their nether regions at a Korean spa, but are horrified when they learn it's a fertility treatment. Two days later, they still don't have an answer to their question. Tyler, who is gay, suggests that maybe it's really a magic mouth, and tells them about the most popular girl in his year at the University of Illinois. The Dirty Hot Guy comes in and Lizzie ambles over to talk to him. He tells her he knows the secret to a magic p**sy -- it's confidence. Just then, his date arrives -- an older woman who exudes confidence and is not threatened to see him with Lizzie. Later, Lizzie tells Sam that she misses Drew, her ex, and wonders if he's happy with his pretty younger girlfriend.
