Sasha Grey, one of the most popular adult film stars today, can now be seen in an ad for PETA promoting animal birth control.

“I think spaying and neutering is incredibly important. … [I]t keeps the animals out of the shelters, and there’s too many unwanted animals out there already.”  – Sasha Grey

In addition to the ad above, there’s also a behind-the-scenes video from the nude photo shoot where she talks about…why too much sex can be a bad thing? Whaaaaa.
