It's time for another installment of Pot Psychology, the "advice" column in which we attempt to solve everyone's problems with an herbal remedy. (Remember, kids: Don't do drugs!) In this episode, the Big Edie to my Little Edie, Rich, helps me answer questions about anal, vaginal, and oral sex. Got a burning question? Send it to potpsych@jezebel.com. (Please keep them short; they're verrrry hard to read when stoned.) P.S. We like pictures because they're easier than reading, so feel free to send some our way.
