What now?

Choose the one that would get assigned to you socially. The gender filter is about what other people want to talk to, not what you consider yourself

You likely still identify as masc or femme in some sense, so chose the closest option.

My point is simply that there is likely a 'closest option'. Obviously people don't have to use any service they feel doesn't cater to them, but when a service doesn't always offer more than the binary it doesn't have to always be a "woe is me, how could I ever proceed" scenario.
