Is being slightly possessive a red flag, or something I need to address?

There’s a man I like who likes me. We’ve agreed to date one day, but we haven’t started dating yet and he subtly checks my iPhone messages, leans over and looks when I receive a new text message from one of my many guy or girl friends (I know lots of people, I am naturally quite outgoing and sociable).

He’s not obsessive; and I don’t think it’s wrong for him to want me to wait for him (not sleep with or kiss any other guys); until we get together and then only with him. He’s not abusive or creepy in any way. I’m just not sure about the phone checking.
