Cuddles
Calling Aziraphale overly affectionate was the understatement of the century. He hugged Crowley as often as possible, Warlock whenever the boy would allow it, and even strangers sometimes - especially when they were aggravated or upset.
Whenever he tried to hug a stranger, they were usually angry or confused at first, but quickly relaxed in his arms. It was a handy trick for conflict resolution. He just had a naturally calming aura.
This calming aura came in handy while dealing with Warlock throughout his childhood – from the terrible twos right up to the boy's teen years. It calmed him when he was throwing a tantrum as a toddler and comforted him through his more hormonal years.
When Crowley has a bad day, when he is infuriated at the actions of downstairs, when it feels like everyone is going wrong, he takes full advantage of this power Aziraphale possesses.
Perhaps it was just an angel thing. Though Crowley found this hard to believe.
He would posit that it was likely a thing excusive to Aziraphale; it was hard to imagine any of the other angels being a good hugger. The image of being held by Gabriel for any extended period sent a shiver down Crowley's spine. No, absolutely not.
"Are you okay dear?" asked Aziraphale as Crowley grimaced mid snuggle. They were spread across the sofa in Aziraphale's bookshop. Crowley was practically lying atop of Aziraphale, though Aziraphale didn't mind at all.
"Just had the image of hugging Gabriel pop into my head. No thank you," he laughed.
Aziraphale giggled, a high melodious sound. "I can imagine. Guess you're stuck with me then. I hope you're okay with that," he teased.
"Less talking and more cuddling," whined Crowley, burying his face in Aziraphale's chest. Aziraphale patted him on the head and brushed his fingers through his lover's bristly red hair.
A few seconds later, Aziraphale noticed that Crowley was being unusually quiet. "Are you asleep dear?" he asked.
"No. I'm not asleep," mumbled Crowley, stretching himself out a little before settling down again.
"If you want to go to sleep, that's okay."
"I'm not sleepy…"
Two minutes later Crowley was sound asleep and snoring softly. Aziraphale smiled a little, right as his leg fell asleep. But he just didn't have the heart to wake Crowley up and ask him to move.
So, he let Crowley nap on him for just a little while longer. He soon found himself dozing off as well.
