For the Miami area...check out these two sites:
www.miamicompanions.com or
www.theeroticreview.com
The TER website requires a membership to access the VIP area, but you can still use the site to find escorts in the Miami area.
The VIP area gives you access to reviews of these ladies, with some detail on what they will and will not do (cbj vs, bbbj)...That kind of stuff...A bit like the Device.
And...yes...I've got a VIP membership...submitting reviews of girls gets you 15 days free...I find this information very helpful when making my choices.
Hope this helps...
Cheers,
