If a guy comes to Rio de Janeiro and:
1. lives somewhere that is not Zona Sul or Barra for a couple of years,
2. befriends the locals
3. eats in cheap popular restaurants,
4. goes to common cheap botecos for a drink,
5. hangs out in a non-touristy roda de samba,
6. nightgames in Lapa and witness the local thugs muggery,
7. interacts with native bums and crackheads
or he does something equivalent for each one of those items; then I might consider him somehow knowledgeable of the place. Btw, I haven't done only one of those
Now a sex tourist comes here for a couple of months, stays in a insulated neighbourhood, goes to insulated venues, fucks a couple of gringo hunters or straight up P4P and claims he is an expert in the place?
Seriously, you're just a gringo tourist with game
I'm not even hating, I'd love to do a similar trip to Thailand or Eastern Europe but to claim you're an expert just because you drilled some local pussy is either dishonest or deluded
