Is my waist too small?

I'm genderfluid and I haven't been on any hormones, I haven't had any surgeries, nothing like that since I'm closeted and 15. I've always thought of my waist as on the bigger side since I'm chubby but when I'm a boy (like right now) it feels too small? I don't know if it's just my mind playing tricks on me or something. Like it seems insanely feminine now when I've always been insecure due it it being the opposite in my head.

It's like I'm thinking what I always wanted to think about my body but it's still bad.
