A period sex anthem exists ― and, of course, it’s sung by “Crazy Ex-Girlfriend’s” Rachel Bloom.

The CW’s musical comedy TV show is known for tackling feminist issues and plotlines with wit and humor. But according to Vox, having sex while on your period crossed the line for CW, and the network opted not to air Bloom’s minute and a half ode to period sex.

On Friday, Bloom ― the writer, star and co-creator of “Crazy Ex-Girlfriend” ― uploaded the full “Period Sex” song and video to YouTube.

One more thing: the full version of "Period Sex" is too dirty to air on tv so it will be online-only. #CrazyExGirlfriend — Rachel Bloom (@Racheldoesstuff) January 14, 2017

As usual, Bloom and the “Crazy Ex-Girlfriend” team’s ability to bring levity to a taboo (err... messy?) topic did not disappoint.

The catchy anthem includes gems like, “Put down a towel and party ‘till it’s dry with some period sex,” and, “Think of it as Mother Nature’s juice cleanse.”

Watch the full video above to jive to some truly awesome “period sex” tunes.
