Was Myles Toyne gay?

For many characters, GRRM does a great job of making them dynamic characters who happen to be gay, unlike the show where that became a character trait.

Outside of Daemon II Blackfyre, Bokkoko and Xaro (and a few others) GRRM is pretty subtle when it comes to this, especially with Jon Connington (who GRRM likely confirmed was gay):

Q: Is a certain POV character in ADWD gay?

A: "I can't answer without spoiling, but if you're talking about what I think you're talking about, then yes." George mentioned that there are gay characters in ASOIAF. He mentioned Loras & Renly, saying that he included "what I thought were subtle but clear hints. HBO was not subtle about it."

And we know how JonCon viewed Rhaegar:

The bells tolled for all of us that day. For Aerys and his queen, for Elia of Dorne and her little daughter, for every true man and honest woman in the Seven Kingdoms. And for my silver prince.

But lets look at how JonCon viewed Myles:

JonCon's comments about Myles likely mean they were just old/good friends:

You do not know these men, my lord. It has been a dozen years since you last rode with the Golden Company, and your old friend is dead."

Blackheart. Myles Toyne had been so full of life the last time Griff had left him, it was hard to accept that he was gone. A golden skull atop a pole, and Homeless Harry Strickland in his place. Lemore was not wrong, he knew. Whatever their sires or their grandsires might have been back in Westeros before their exile, the men of the Golden Company were sellswords now, and no sellsword could be trusted. Even so …

and:

Blackheart, his men had named him, for the sigil on his shield. Myles had loved the name and all it hinted at. "A captain-general should be feared, by friend and foe alike," he had once confessed. "If men think me cruel, so much the better." The truth was otherwise. Soldier to the bone, Toyne was fierce but always fair, a father to his men and always generous to the exile lord Jon Connington. -ADWD, The Lost Lord

But this comment here has always thrown me off a bit:

"Which one is Myles?" Griff found himself asking.

"There. On the end." Flowers pointed. "Wait. I'll go announce you." He slipped inside the tent, leaving Griff to contemplate the gilded skull of his old friend. In life, Ser Myles Toyne had been ugly as sin. His famous forebear, the dark and dashing Terrence Toyne of whom the singers sang, had been so fair of face that even the king's mistress could not resist him; but Myles had been possessed of jug ears, a crooked jaw, and the biggest nose that Jon Connington had ever seen. When he smiled at you, though, none of that mattered. -ADWD, The Lost Lord

I don't know, it seems somewhat like the "silver prince" comment in which JonCon is thinking about his love for someone. That said it could be that they were old/good friends or that JonCon just crushed on Myles.

TLDR: JonCon's comment with regards to Myles Toyne's smile has always thrown me off a bit and has me considering that either JonCon had a crush on him or Myles was also gay.
