Curious as to which locker room I should use as a trans woman.

So basically I’m trans, not 100% passing but I’d say I’m pretty much right in between like a 50/50. I don’t wanna make women or men uncomfortable and unfortunately the gym doesn’t have a gender neutral bathroom. What would you guys as a society find most appropriate my goal is to make the least amount of people uncomfortable and I’m unsure what locker room to use. I typically use women’s bathrooms but obviously that’s different than a locker room where women are naked. Any advice is appreciated thank you guys!
