Now, you might be thinking that it's a bad idea for PBS to start showing pornography when people like Romney are dying to cut its funding, and you're absolutely right. However, this isn't porn! This is educational programming featuring the legendary sex educator/author/artist/activist Betty Dodson, and frankly, this is information that people need to have. If you, incidentally, feel sexual arousal while Carlin Ross is pleasuring herself according to Betty's methods, well, that's all you. There's nothing obscene or indecent about it; it's as Betty very flatly says when Carlin is done coming, "Good."
Sidenote: imagine if every time you orgasmed, you heard Betty Dodson's monotone voice say "good" in your ear. You'd probably have ten times as much self-esteem and confidence.
