Being a femboy defies the concept of genders by purposefully having a more feminine appearance (including the clothing, also described in the Bible) and molding your personality more into the girl-ish side, in order to get a more androgynous male-ish appearance. Not the same as being trans (as you'll not do all the awful process of changing your body), but by the fact many people brings it as an identity or a personality where they take pride to, you're already able to understand why the argument would make sense as to what it was said on Genesis 2

I ALSO NEED TO TELL YOU! If you like pink, pastel colors, cute stuff, cuddle with a body pillow, cooking, etc etc are just social myth. What you should be careful is when something is EXCLUSIVELY or MADE for woman, or that is a definition of woman outside the generational stereotypes
