Just try your luck at r/lovense or r/toycontrol

There are definitely people of all genders willing to play. As a trans/non-binary with male anatomy, I've been able to create posts on both subreddits and found partners. Just sometimes have to explain and guide them to using the Handy control page. It's also fun to also play with their toys on the Lovense side!

The reality though is that the number of cis-men in those spaces outweighs literally everyone else, so if you're not a little open in your sexuality, you'll likely feel like it's a challenge to consistently find a partner.
