When your kissing your boyfriend, slide your hands up their shirt and massage his chest and abs with your fingers. :)
He will lean into you (mine does) and hold you closer. And he may go a little dramatic in the kissing. But when touching his body, be gentle (as if you are tickling him somewhat). Also as this continues, from kissing the insides of his mouth, begin tongue around his ears and then head to his neck with a bit of a sucking to your kissing there. This better standing up.
