Was leonardo da vinci biual or gay?

From what I can understand he was a (gay). THE MONA LISA, was one of his companions, a dude. Evidence in her/his eyes. Scientist found the companions initials and a number using special gear. Leonardo was arrested once for "attacking" someone ually but was released later due to lack of evidence. Leonardo never had kids, married, or was involved with women. He did have many paintings and notes that included naked men, but i don't think he has some of women.
