What are the rumors about Duarte's sexuality?
Lifelong "bachelor", last in his "Royal" line, never seen with a woman hithertofore, then....quite suddenly....marriage to a (much younger) suitable woman who had never been heard of before...the math adds up.
Once I watched on Youtube an interview with him from 1994 and he said that he had some girlfriends but he didn't married because they were very complicated. He also said that after try and try he decided to stay alone and wait for the right girl. One year after this interview he married to Isabel. By the way, they meet each other at her house (he was a friend of her father) when she was just 16 and he was 37. Another interesting fact is that he taught her how to swim.
