Try doing an unusual race Saiyan.

There are folks who hyper sexualize any female being but it might be easier for you if you write as like an Argonian, or Khajit, or Dwarf, or Halfling woman.  I did a similar thing to stop writing block head bad asses by writing a lot of doctors and reporters and detectives and just general non-warriors.

Turns out they're a lot of fun to write.

The female character I want to write is a combination of both those things - non-combatant and a non-human non-sexpot woman.  Nice to explore new territory.

Or take it to an extreme and do a basic parody/exploitation/deconstruction of the sexpot bad ass fantasy girl.  That could be fun too.
