"After all, it seems you want it bad enough to leave your old gender identity behind, it might be a lot LOT deeper than -just- sexy reasons"
Not true, actually. A common trait of autogynephiles who transition late (and seeing how Strype is in his late 30s and transitioned in 2019 according to his Furaffinity, this fits the bill) is that the fetish becomes so uncontrollable that fantasizing and crossdressing in private isn't enough to satisfy it, and the autogynephile develops late-onset gender dysphoria as a result. If you're willing to drop everything you have going in life (your job, your marriage, etc.) just to fulfill a fetish then that's actually a sign of a deeper mental illness (but we knew that).
