I've only seen series 1 that was enough. But I'm thinking of reading at least one of the books. Explicit scenes don't affect me as much if they're written down.

It seems like TV has run out of taboo subjects now GoT is so popular. And I'm sure if I did some research I would find medieval english aristocrats bedding their family members in actual reality. The only actual one I know about is the Romantic poet Byron but that was later.

I would love to know in more detail what inspired George R R Martin to write themes such as incest etc.....
