Im quite certain its natural evolutionary instincts.
A woman past 30 has little time to produce children.
If woman over 30 were suppose to be attractive, push up bras, and makeup wouldnt exist.
Right, they start fucking for fun after 30. And depending on genetics and lifestyle, they can stay hot until their mid 40s
Just because they physically peak in their early 20s doesnt mean they sexually peak then as well.
Btw, youre trying way to hard to sit back and applu logic to a situation in an attempt to understand something that is illogical....
You have to actually DEAL with women anf experience.it before you can come to any sort of conclusion.
You cannot sit back and use logic, nature, and evolution to understand women. You simply cannot do it. Women must be experienced to even get a slight grasp of their existence.
