Be mature and try to process it

You think back to what happened just a few hours earlier - your old 'playmate', Tim the stableboy, had led you to one of the derelict rooms in the east wing of your father's castle. This is where you'd been meet 'your men' over the years. It was a quite, albeit drafty, area tower which the castlefolk tended to avoid, hence it was the ideal place for you to hook up; so ideal, in fact, that your idiot older brothers still don't know that you are as gay as a rainbow flavored unicorn.

Tim had rounded up your usual gang for your pre-birthday party - Steph, the Lord Commander's son; James, a pageboy; William, a local lord's wastrel of a nephew; Alex, a freshly minted knight, and a few dozen other boys you never bothered getting to know.

The ritual was always the same - you carefully cross the courtyard with Tim, duck into the stables, hoist a ladder up to the first floor window of the east wing, and climb in. Once in, it's strictly no clothes allowed.
