Luffy.

You recently started dating Luffy. He was nice to you and gentle, but not passionate or lustful. You haven't had sex, he doesn't really like intimate touches and you began to think he was pushing you away on purpose until you saw the Medusa tattoo on the right side of his stomach.
Luffy was lying next to you trying to fall asleep, but you woke up, hugging him to which he flinched feeling a little uncomfortable and trying to push you away.
"Honey, take your hand away I really don't want to hug you right now."
He whispered softly to you, but you ignored him wanting to take his shirt off to which he blanched without waiting for that.
"ENOUGH!" Luffy pushed you away and sat on the bed holding back vomit and you were shocked to notice the tattoo on the side of his stomach.
