Follow up on JjBee's advice
Great advice from JjBee. I haven't been to Medellin but lived in Bogota for 7 months. Had too much fun in Santa Fe. Will definitely head to Medellin when the borders open up.
I would buy a 3 pack of chocolate bars (Casino brand) from Carulla for about $3-$4 dollars and give one to a girl I liked or repeated with as a treat. What girl doesn't like chocolate? The girls were excited to receive it and became more enthusiastic. Most of these girls don't shop at Carulla so they don't know it's cheap. I wasn't giving out chocolate bars to everyone. This process was beneficial, Troya and Paisas club girls would head to my nearby hotel (1 block away) before their shift for a more relaxed session. I abhor that knock on the door at the clubs.
Every girl is different, but a little flirting, jokes, or an unexpected small gift will get them to open up. At least for me, it's better than a mechanical session. I avoid the girls that are bitchy or bad sessions. It's funny how those are the girls that are always trying to get you to session with them again or aggressively looking for new clients.
