I just came back from a short biz trip to Bogota. While there, my wingman and I hit many of the Bogota hotspots...and we were also comparing the Colombianas we observed there with those that come to Panama and San Jose. In response to this thread, thought I would share a couple observations.
First, like someone else mentioned, you cant blanket categorize the working girls. They come in all shapes, sizes and mental states of being. You have your newbies, your longtimers, short timers, part timers...smart ones, dumb ones, cute ones, ugly ones...and what is even more interesting to me is that ALL of them get action at some level or another. This probably represents the variety of men that hook up with this variety of female providers.
I have recently met a couple Colombianas in Panama who are working but not hardcore. ONe in particular has definite goals financially of how long she is working in this in order to build a house for her family back in Bogota. Parents dead...and she is supporting a young son and her sister and brother back in Colombia. Definitely has a more marture outlook on life and even the business...has been fun company for a buddy of mine...and I would say we are friends. Verified all of this by meeting her family in Bogota this week and helping pass along some papers from the sister in Panama. Very nice family and people...her story verified though they have no official idea of what she is doing in Panama. They think she is working in a Casino. I guess she is in a a way

... Anyways...I dont think this is the "typical" girl in this profession. And hopefully, she will find her desired exit from the biz on her own terms.
On the other hand...my friend and I toured a number of mongering establishments in Bogota. And while it was entertaining and all, we actually found a lot of "hard core" Colombianas in this scene in Bogota. They are definitely different than most of the "fresh" attractive girls you see all over the city. We went to a high class place called Club 49...lots of pretty girls...but the "gringo" price was too high and we passed. From there we went to an after hours place...which I dont remember the name unfortunately...but it is known as the 3AM destination for all types of working girls after the bars and strip clubs close at 1 or 2AM...which is most of the establishments in Bogota. Sure enough...taxi after taxi of chicas started pulling up to this large house/club at 2:30AM...and by 3:30...the dance floor was packed with working girls dancing mostly by themselves or each other...and guys standing around picking out what they wanted. It was a very interesting scene...mostly younger people...NO gringos...and no one our age really. My wingmans claim to fame that night was being "shut down" by a hooker...the only one he found interesting. We took it lightly...but it was obviously as much ladies choice in this place as vice versa. I found myself turned off by the place because most of these girls reminded me of the "Maria" that Trailor Park leads this thread of with. Burnt out young girls (some looked underaged to me)...most of them with a druggy glaze/haze in their eyes...and most of them available in the attached "hostal" for a quick $20-30 blowjob or Quicky. There were no potential GFs in this crowd...and I really felt I was among the lost and forgotten girls of Bogota.
To leave on a positive note, there were many bright and "fresh" girls that we met over a couple days at the hotel, through biz meetings etc. There are many beauties in Bogota as elsewhere in Colombian. But truth be told...the hardcore sex providers are not what most of us are really looking for in a woman. And to try and have a "GF" relationship with one is truly foolhearty in my book. These experiences made me even MORE thankful for my Colombiana GF...
