No, of course not. I bought a video with the same woman (and presumably same penis) along the same lines that was a little too psycho for my tastes, but I'm sure some people like it. It was called "Psycho Girlfriend Circumcision," so no surprise there.
I see in the preview that she draws a line down the length of the underside of his penis. I've seen this confusion a few times and I think that some women think the penile raphe is a result of circumcision.
