Its not that deep. Just use imagination
You seem new to omegaverse so… Alphas can impregnate so they HAVE to have testicles to house the sperm and they have to have a penis to get the sperm to the cervix. They have female anatomy because they are female. The two are not mutually exclusive. You are [female/male/intersex] and also [omega/beta/alpha] on top of your original sex. So a female alpha has a penis and a male omega has a uterus. Betas have normal human functions like you and I. If you don’t like that, don’t read omegaverse.
get over it
some woman have dicks in the omegaverse and real life, not a big deal, just read something else if it makes you that uncomfy :8
Dude I thought this was gonna be a cool manga but no the chicks have dicks AND vaginas. Why is the clot nestled below the balls???
