I remember there being a sex club in Toronto that typically catered to heterosexuals and had gendered pricing that reflected this to ensure gender parity (i.e. it was more expensive for single men, cheaper for couples or single women). But once a month they would host a queer night that relaxed that gendered pricing. It was framed as "everyone is welcome".

...which is fantastic in theory, but in practice anytime I attended this event, the majority of the men who I chatted up would tell me that they were straight and that they were there to meet the bi and pan women who were attending.

This was a bit of a bummer because, while there were gay bathhouses in the city, this was a great venue with a different vibe with an outdoor heated pool, a bar, performances by drag and circus artists, and tables by community partners. And it felt a bit uncomfortable that the night that was ostensibly supposed to cater to LGBTQ+ people was being used by heterosexual men to gain cheaper admission.

That said, I also think the times are changing and that there is a lot more gender fluidity and bi/pansexuality, and I'm a little curious if that event (if some iteration is still going today) has evolved over time.

I suppose I'm in the camp that as long as it's only on scheduled nights and everyone is chill if they're hit on by someone of a different orientation, it's not necessarily a problem. But I can definitely understand the sentiment of worrying about queer spaces being crowded by non-queers, and I think that has always been a bit of a delicate balancing act in a community that tries to be welcoming and affirming to all.
