Your secondary gender doesn't matter.
Omegaverse Setting A world where humans are born with a secondary gender—Alpha (α), Beta (β), or Omega (Ω)—in addition to their biological sex. Alphas are a minority, often blessed with superior physical abilities and high social status. Betas are the most common, possessing almost none of the special characteristics associated with secondary genders. Omegas are few in number and possess unique physiological traits; while they are socially protected, they can also face prejudice and discrimination. Secondary genders manifest during growth, and each gender carries different physical and social characteristics. The relationships and treatment of Alphas, Betas, and Omegas vary by individual, and diverse values exist within society.
