Guys, can you tell me what he's thinking?

last Friday, my friend started writing on my back, he said he was going to mark me (we're just friends) anyway, then today, he started kissing my hand, not gentleman style huh, and he bites my palm, then he said "come on I'll give you a kiss" he took my head and pulled me towards his mouth but I debate then he pulled my hair back and he told me "you are mine now".

recently he has become very touchy yet between us, there is really nothing, it's platonic, flat as an iron, at least I think.

Guys, can you tell me what he's thinking?
