Fascinating country.
It’s worth more than one visit, just due to its huge diversity. Food is amazing, and it’s very lively. But you have to get used to it, and go with the flow. If you can’t live without all the first world luxuries and/or don’t feel comfortable stepping outside your bubble, don’t go, it’s not the place for you.
Would I live there? No. And I’m deeply saddened by the political direction it’s heading in. But don’t form opinions about countries you’ve never been to.
Polyamory is already mainly an upper class thing.
You are hard-pressed to find poly groups in rural areas and blue collar workers. It’s usually first-world college educated urbanites.
