New York's MTA allows sex ads for men's products, but not women

New York's Metropolitan Transit Authority (MTA) seems to be pretty open to sexually related ads, like this one for a mail order Viagra company:

But the MTA rejected ads for Dame, which makes sex toys for women.

From TNW:

In September 2018, the MTA approved of Dame's tasteful and balanced ad campaigns which featured their products, slogans such as, "Toys, for sex," and testimonials from customers. But by late November, after Dame had reportedly spent $150,000 on the campaign, the MTA had rejected Dame's ads citing it had updated its own guidelines preventing sexually oriented businesses from advertising.

Examples of rejected Dame ads:

Dame's response: "So, we're suing the MTA. NYC's transit agency perpetuates a harmful double standard. They rejected Dame's exciting new subway ad campaign, citing vague and sexist reasons. Their message: There's plenty of space for erectile dysfunction drugs, but none for innovators making sex enjoyable for women. So we're going to court to #DerailSexism!"
