He can't help but tear up slightly when he hears those words. He might be a demigod, but he still more or less looks like he did when his powers were awoken. Which means he's still a skinny and insecure teenager, desperately trying to pretend that he's not insecure about his lack of muscles or cool tattoos or anything like what he sees online - even the twinks look more muscular than him.

He kisses his boyfriend back, touching the other's sides carefully before pressing his hands to Shang Beida's back when he doesn't flinch away. He opens his mouth and clumsily runs his tongue against his boyfriend's lips and... gods damn him to every Underworld but even just his lips taste like the nectar of the gods. He pulls the other close and - he pulls his face away for a moment. "... Do you have a way to heal yourself if I... um. Leave marks?"
