There's two sides to gender-bending imo.
The gender dysphoria is a big one, at least for me. Gender-bending is what got me to look into gender identity and helped me to start figuring out my own. It's healthy to think about your gender and explore yourself.
Also, R63 is popular in the fandom because that's what furries do.
There's no need to hold yourself to ideas of what you should be.
If I hadn't started exploring past that, I would be spending the rest of my life miserable instead of finding new joys everyday.
