Human Females are almost always carrying fertile eggs and producing pheremones and hormones related to the act of reproduction.

The monthly cycle is as such:

1. Primordial Follices form in the walls of the Ovaries

2. Primary Follicles and Secondary Follicles continue to grow and expand until the egg cells are surrounded in cyst-like antrums, known as an Graafian Follicle

3. The first Follicles to rupture release the eggs, AKA Ovulation, and the rest of them still developing in the walls die off

4. Large amounts of Uterin Flesh is shed to allow for regrowth (painful and bloody)

If you include every individual stage of the egg production and the healing there are about 8 or nine steps/phases.

Also Human Males, a lot of Males in general actually, would fuck a mailbox any day of the week if it had some pheromones coming out of it.
