Yeah, I think the first time I "experienced gender" was that period of time when my kid knew "mom" but not "dad" and even though he meant it in a gender neutral way, I still felt strongly that it is wrong.
Children do this experimentation naturally but are shamed out of it and railroaded into their sex assignment even though you’d get the same result for 90% of kids by just letting it run its course. The fact that there are adults who haven’t experimented with their gender before is a sign of major societal repression.
Mine is similar: You can only be true cis if you are confronted and in contact with all faces of your sexuality. Everything else is compensation and/or unhealthy.
