Hey man, hope you have a great time here in Medellín, I don't really recommend the girls from bars or strip clubs, some are hot but with a "Diva" attitude, very restrictive with what you can do to them, and a lot of times are more expensive compared to girls with their own apartments or "Casas" like "Ellas Erotic" or "Zandaly". Try to go with girls that have good reviews from this forum, or experience places like "La piscina SW" a swinger bar that has gang bangs on tuesdays normally.
