They go from being "hot for a guy" to desiring a real man. When they birth that baby that changes what they see as "hot" in a man. Suddenly they get turned on by maturity or being settled or some other quirk that never crossed their mind previously.
I have had coworkers and others that I know who were suddenly flirty or wanting a lot of time with me or see them into wanting it with other men not their spouse or father of their baby. Oftentimes, they are very open too about all things sexual and sexuality whereas before they would not have been that way.
Do others see this change too?
How many women here saw changes in themselves after they birthed?
A woman that used to work for me was always a good worker, every now and then she may have threw a flirt my way before she birthed her son. After a year of being a Mother and trying to deal with the father of the baby she came to me for advice. I bluntly gave it to her. I asked her about the perceived changes that I saw in her and she replied, "I liked fucking boys before I became a Mom. Now all I can think about is if I fuck it has to be with a man."
