Do female pimps exist?  Have any of you worked for one?  How are they different from male pimps?

Agency owners (that are female, obvi) are technically female pimps aka "madames". They take a cut of your money just like a male pimp would (do those even still exist? Honestly?! Lol!).  

When I think of madams I imagine a lady running a escort agency.  I was thinking more of a thuggish  or street type of female pimp.  The kind with the fancy car that drives the girls from city to city.

they are often ex-working girls themselves.  They usually run higher class call girls whereas pimps usually manage streetwalkers.  Many agencies are run by madams, and many of the Kgirl bookers are retired Kgirls themselves, although there are also male Kgirl bookers.  I never heard of a pimp that was actually a man-whore first.

The internet opened up the business without having to rely on Pimp to get clients, now girls like to be treated respectfully, the whole mean Pimp stuff was back in the 90s,,, the girls who still like to be managed work for agencies mostly female owned.  

Even if the overall job function is the same.

First of all Male Pimps are more likely to rape their Whores then Female  Pimps.  

but unfortunately pimps do still exist and yes some of them are women. I have read a few legitimate "human trafficking" cases where it was a woman controlling, abusing, and "turning out" other women (girls) against their will.

Human Sex Traffickers

the girl doesn't have to suck a dick
to get the "better" clients,  
when she's working for a woman.
A woman will expect the girl to be accountable for her actions.
That "sweet-talkin' " shit won't work on a female.

There was a story a year or two back about a couple of women who kidnapped a younger lady and pimped her out against her will. Clearly pimping and trafficing. They're enjoying federal hotel accommodations, next 20 years or so I think, via the taxpayers. In this case I'm quite happy making my contribution.

With you on the hope we could see that aspect fade away. I think legalization would do a lot of good for many but it, unfortunately, would not end the situation. In some ways I almost fear legalization would then result in the pimps* and trafficers moving into even more disturbing types of forced services -- resulting in the victims having an even worse time of things. That of course is premised on the idea they are not already at that point in a majority of cases.

Prostitution is legal in many countries in this world, and in most cases where prostitution is legal, pimping is illegal, and since the hookers have full protection under the law, pimps are almost unheard of in those countries.

'Pimps' can be a wealth of information. They know the game and can school newbies. How to keep safe being the biggest thing. They know stuff no girl who is just getting into this all by herself has any real clue what is involved.

legalization comes with other barriers to safety and well being of service providers.
