Wait so if they sneeze does that get someone pregnant (if there’s no gender does that mean anyone could get pregnant)
But if the sneeze itself develops into a child I would think advanced aliens would either make the equivalent to protection, a miracle allergy medicine, or just some way to stop sneezing with a medical procedure (sneezesectomy?)
Seems like by natural selection there would be a genetic predisposition to sneezing in their species, until most of the sneeze most of the time.
