All three types of intrinsic s*x emit a hormonal scent (pheromone), with alpha and omega being stronger and beta being almost indistinguishable. Pheromone not only plays a role in reproductive matching, but also the basis for identification between different genders and classes.

Alpha’s pheromone is musk, while omega is similar to beaver. They are all animal aromas. Beta is distributed as an object and is very uncommon.

Alpha has a clear possessive appetite for the spouse, the most obvious being the “marking” behavior. The mark is completed by “knot”, and within one month after the knot, the spouse is marked by the alpha pheromone.

The pheromones of Alpha and Omega are attracted to each other, but this does not mean that there is no room for choice between them. In general, Alpha’s ability to resist pheromones is stronger than Omega; the better the quality of Alpha and Omega, the stronger the ability to resist pheromone temptation.

Omega men and women have estrus, and the length is about three days. Estrus interval, female omega for one month, male omega for three months. During estrus, male omega cannot eat and excrete normally.
