So Leonardo da Vinci was NOT gay? What about the sodomy trials?

There is no absolute evidence that he was or he wasn't, but it's significant that he was never known to have been with a woman at any point in his life. What truly straight man spends his entire life without female companionship when even the ugliest man can find some sort of woman because male/female relationships are completely accepted? On the other hand, there can be and in his case was some compulsion for a man to stay closeted his entire life just exactly because of the risk of things like the sodomy trials that you mention.
