Is Medellin still a decent destination for mongering?
Not really.
It is now comparable to Panama or San Jose Costa Rica and similar much safer Central American places.
Frequent and infrequent mongers alike know this to be true.
Your best chance to enjoy a Colombiana is now outside of Colombia.
Start by looking in your private reserved Arab harems spread throughout the Middle East.
If you have access to one.

Medellin. Long Term versus Short Term
There is a big difference between guys staying here for a while and those visiting for a short time. Guys staying here for a while aren't trying to maximize the number of times that they have sex. They have sex when they feel like having sex and there could be a number of days when they pass on it because they don't feel like it. That is not happening with guys on a short visit. Long term guys also can establish a relationship with girls and for those asking for money, the girls may be willing to accept a lower rate from the long term guys than the short term visitor because the long term guy will be around for a while. So, the price long term guys pay may not be the price that a short term visitor will pay.
This website is a mix of short term and long term guys but the objectives are different.
Now I am actually visiting Medellin for a few months so I can take my time. Most days are just me doing what I usually do at home. I am retired now but I keep busy with some remote work and trading in the market. The biggest different from home is that when I feel like having sex with a young attractive woman, it is easy to arrange. Does Medellin or Colombia work as a long term place to stay? Yes, but you need to start learning Spanish if you don't already speak Spanish. Most of the long term guys speak Spanish at a decent level but I am still at the learning stage. There is a big difference in life in Medellin if you can speak good Spanish. That is not a surprise but it requires time and effort to learn Spanish and most guys don't want to do it.
