How to turn him on

My man and I haven't had sex yet. We're waiting until we've been together a while longer and we both feel completely ready (we're both 18 and virgins) However, things still get pretty heated when we make out. I love when he gets horny when we're making out because he becomes so dominant (he's normally the sweetest, most respectful man I know) What can I do to really drive him crazy?? I know he loves when I start kissing his neck, but is there anything else I can do just to tease him?
