You remember there being something called "the gate" in one of the halls. It was entirely experimental but it could help you. It allowed a user to access alternate versions of themselves, or at least it was supposed to, most thought the gate was just a clean out for those who had become dissatisfied with their changes, or whose changes are considered disatifcatory to the world. Or an example of social darwinism for those who had gone to far.
You make your way to the gate experiments. To your slight embarrassment you realize it's not an actual gate. The doctors explain to you that they're going to send you to a universe where you fit, one where the changes made are normal. The reason for the gate is so that people whose changes wouldn't be accepted can go somewhere were they're normal. It didn't sound that bad, if you're stuck without genitals or gender it's better to live in a world that has no knowledge of those things.
However alongside that you were also informed that death or other horrific side effects could befall you. Not that death really seemed like a bad idea right now. Fuck the side effects, it's better to have a chance at a normal life rather then be a freak forever.
Before you decide to sign the waiver someone tells you, "remember that this is only an experiment, this isn't necessarily going to work out."
You sign the waiver silently and things begin to be plugged into your head, you're put on a chair that seems to be lowering into something. No going back now, it's time to become a brave explorer of spacetime, or dead.
Everything goes black for a second. You can't see hear or move. Then suddenly you wake up in bed. You look out a window to see you're in a strange city that's not your own. It looks modern technologically, but completely alien to any culture you know of, strange neo Roman architecture and large bridge like structures that don't exist in any city on earth.
You look down at yourself, still sexless but hopefully that's acceptable here.
You look out your window to the streets and see people walking around nude. Some wear clothes, but most people who are young and attractive go around nude, they wear a lot of jewelry and accessories all over their bodies but nothing to cover their chests and crotches. As you look closer you see there's nothing to cover, everyone you see has no genitals or sexual features.
It still sucks being sexless, and in this world there's really no going back as nobody would even know what gender is. But because your normal it doesn't matter, there's nothing to be upset about now.
