A couple had full-blown intercourse on the Vienna metro. When other passengers realized what was up, they fled—then, slowly but surely, crept back to watch, cheer, jeer, photograph, and film it. Is this a triumph or a travesty?

The subway sex-havers of Vienna: A point/counterpoint debate. (Warning: The above video is R-rated.)

They're heroes
by Brian Moylan

OK, clearly people doing the nasty and leaving their bodily fluids in a public space is pretty darn gross, but it's also really hot. Who hasn't ridden the subway late at night and saw a comely gentleman or lady and their thoughts turn romantic—or actually sexual. It's such a taboo, something so public and transgressive that it makes the act of doing a little choo-choo in the underground tunnels even that much more attractive. God knows if I was on an empty subway car with an eligible gentleman who seemed willing that I would try some shenanigans. We shouldn't fault these people for having the balls (and ovaries) to fulfill something we all fantasize about. Yes, I know it's wrong, but that's part of the appeal. And good on the people for cheering and filming. If someone is so A) crazy or B) exhibitionist to knock boots on public transit, we're happy they're getting a good reception. People should behave themselves in public, but it's nice that human sexuality isn't getting the knee-jerk Puritanical disgust that it often gets. The scene probably would have ended much differently if the two weren't young and attractive, but that's a whole different argument.

They're villains

It's bad enough when creepy men wave their penises at strangers on the subway. Actual intercourse in front of a captive audience is clearly worse! A prolonged act that draws unwitting bystanders into its fantasy, with no escape for those who don't want to partake, who don't want to see, hear, or—dare I say?—smell it, because the train is moving, and some of us are too chicken to open the door that lets you walk between cars, lest we fall between them and die. Do you really want me to die beneath the electrified wheels of a speeding subway just so you can have some live action porn, Brian? This is not an issue of sexiness; it is an issue of riding the subway unmolested. (Not rape-molestation. Just annoyed-molestation, like when you get stuck sitting beside someone with a jimmy leg on the bus.) Besides, subways are disgusting enough without the addition of sex juice and butt grease. Though I admit to being impressed with the subway sex-havers' gumption, I remain resolutely subway sex negative. I am, however, subway sex video positive, as horror erotica for germophobic voyeurs.
