I feel guilty about wanting straight hair

I [28F] have basically wanted straight hair all my life. I like curly hair on other people, but I think it just doesn't suit me well.

I briefly straightened my hair all the time when I was like 12 to 13, but it was time consuming. I've been trying to cope with my curls for years now, but no matter what routine I use I am NEVER satisfied with it. Lately I'm thinking about getting a keratin treatment and really trying to keep my hair straight.

The thing is I feel guilty about wanting straight hair. I am Maori and the curls come from the indigenous side of my family, so in a sense I feel I am dismissing my culture. Straightening my hair feels like trying to straighten myself or something? (I'm also bisexual so.)

Does anyone else have these feelings? How do you cope with them?
