Luffy was clingy with you during the ride to Whiskey Peak. His rubber arms around your waist as you look through the biculars. He would give you small kisses on your head or cheek.

Sanji was a bit jealous but knew that he shouldn't intervene since you and Luffy are childhood friends.

Mr.9, a guest(or a hostage?), was flirting with you... Luffy was jealous.

"Buzz off, Mr.9. Their already taken." Luffy said, being jealous, his rubber arms around your waist, glaring at Mr.9. You blushed.
