promiscuous women are sluts.
why, you will find a lot more sluts out there than "studs."
and when you compare numbers, those sluts could easily outdo the studs without trying.
Girls could fuck 10 different dudes a day if they wanted to, its not the same for men. Its funny how most men will agree, and most women will disagree - it shows the differences in the thought process, women just don't know.

Its a simple game of supply and demand. Sluts are highly in demand, every dude wants to get laid, but not the same is true for every female.
In a controlled environment of 100 men and 100 female, 95 of the men will want to fuck any time they can. maybe 10 of the females will want the same.. what happens - those 10 females will fuck maybe 50 guys, while those 50 guys can only fuck 10 girls. This just a hypothetical example.
