It’s an incompetent query, only there to increase trans traffic on the forum. Why?
He’s “only thinking” of going.
He hasn’t decided on a city.
He hasn’t done any research on existing forum threads.
The interest in trans on the forum is not very great.
Specific trans experience in a country that again, not that many visit, I’d likely to be rare indeed. I’ve followed the Brazil threads and never seen any comment on trans (other than avoid ladyboys on Avenida Atlantica as they have a long-standing reputation for violence and robbery).
