Old beliefs.

Having been born and raised in Latin America, where the culture is so related to the superficial, and having moved to Europe, where all these free ideas of polyamory are on trend, it is really hard to get anywhere good trying to accept it. 
I only got to know the concept of polyamory a few years ago. Before that, I've only known that polyamorous relationships are just man who can't control their sexual urges, phrases like "you can't have it all", and just bad libertine shameless people. 
The same goes for being bi, I only got comments like, "they conform with everything", or "any train works for them", but only and I mean it, ONLY in a bad despising way. 
Being bi and poly is a really hard thing with these conditions.
