The Mexico City Metro is startling riders with what is being called a 'sexist,' men's only subway seat that features a molded plastic nude male torso — complete with a flaccid penis.

The anatomically correct seat is accompanied by a sign that reads ‘exclusive for men’ — the sexist part of the seat — and 'It’s uncomfortable to sit here but it doesn’t compare with the sexual violence that women suffer in their everyday lives.'

There's even a video that shows passengers raising their eyebrows in disbelief at the scandalous seat and absentmindedly sitting down on it, only to immediately jump up upon feeling unexpected bulges in place of the usual smooth plastic.

There's more to the seat than just trying to get a rise out of riders, though.

As the slide at the end of the video notes, 'Nine out of 10 women in Mexico City have been victims of some form of sexual violence.'

The idea behind the campaign, which was launched by the Mexican government, is to raise awareness of the fact that 65% of Mexico City women revealed that they have been sexually harassed — including being groped and cat-called — while traveling on the capital city's bus or trains.

However, they are unlikely to report these incidents to authorities to the frequently male authorities, according to Whimn.

The Mexican government has also tried to combat sexual harassment on public transportation by reportedly starting up an anonymous, all-female public transportation police unit, charged with catching gropers in the act in subway cars.

The brains behind the 'penis seat' — or 'Seat Experiment,' as it's officially known — also created another sexual harassment awareness video project, called 'Experiment Screens.'

In that project, rear ends of random men on the Metro platforms are filmed and broadcast on TV monitors posted along the platforms. When they finally realize their posteriors are on camera, the men attempt to cover their bottoms and appear to be annoyed or upset by the attention.

At the end of the video, a legend reads: 'This is suffered by thousands of women every day.'

The 'penis seat' can be found on a train running on Line 7, between El Rosario and Barranca del Muerto, according to Proceso.
