does he know you're dating? if not, prep him with bringing up there's this guy and tell him how it came to be that you got together, would you like to meet him? on the actual introduction act normal, casual, and relaxed. Dad this is "his name", "his name" this is my dad "you're dad's name". I would recommend first and last if you're dad is pretty formal or if you're boyfriend doesn't know you're last name, then let them take over
Talk about him at supper time if you all eat together . How you met this really nice guy and so on once they heard his name enough they will ask you to bring him over to meet. I'm taking it your of high school age yea?
