How do my characters say "I love you"

Ky Kiske blushing like mad, he has to take a moment to compose himself then he either blurts it out or whisper it in their ears

Snake He doesn't, because he's an emotional mess, the closest he gets is to rain sappy compliments on them.

Sinbad He has a difficult time actually saying it, because he knows words can mean jacksquat, but he would take his lover's hand and put it over his heart, so they can feel how his heart quickens in their presence before whispering.
