More places need to have uni-sex bathrooms in my opinion. We have them in our homes, why not in public too? The option should be there. Trans people shouldn't always have to use the disabled access bathroom. I think we feel judged doing that, because our condition is invisible and we don't want people to think we don't deserve to be there.
It's quite a strong issue, I understand why separate bathrooms exist but a third option is needed too.
