The late 15th and early 16th were particularly difficult ~ Latin had a fixed spelling but maybe a dozen versions of Gallo were spoken in France and in the English court, and lord only knows what they spoke in Scotland in those days ~ or how they spelled it.
Normal fistfighting hard drinking gentlemen began letters to each other with "My dearest" and "My love" ~ with totally different meanings than you can imagine today.
Indeed, and sleeping in group situations with other men was not at all uncommon - as with Lincoln - it implied nothing in terms of sex.
But with King James there are multiple independent lines of evidence that he was homosexual. They had the contemporaneous saying “Elizabeth was King, now James is Queen”, we have the numerous male “favorites” of the King, we have the (recently discovered) secret passage between his bedroom and his “favorite”, we have contemporaneous reports of him calling another man “wife” and he calling James “husband”, we have contemporaneous reports of them kissing in public (and not the kiss on the cheek that was common(and still is in some cultures)- but a noteworthy kiss), and we have records of the letters he wrote to his male lovers, and we have the fact that he was buried between two of his male lovers.
Against all that we have your condemnation of any historical record as spotty and circumspect; thus your decision to ignore any and all evidence that doesn’t fit what you wish to believe.

What can we know of the private lives of early British sovereigns? Through the unusually large number of letters that survive from King James VI of Scotland/James I of England (1566-1625), we can know a great deal. Using original letters, primarily from the British Library and the National Library of Scotland, David Bergeron creatively argues that James’ correspondence with certain men in his court constitutes a gospel of homoerotic desire. Bergeron grounds his provocative study on an examination of the tradition of letter writing during the Renaissance and draws a connection between homosexual desire and letter writing
