Meeting my boyfriends parents

Brooklyn`s
I'm 17 going on 18 and my bf is 19 we've been together for a year going on 2 .He has met my mom and siblings they absolutely love him and he loves them too ,well I would assume he does lol.But anyways I have yet to meet any of his family members besides his close friends.The only time I have ever been to his House is while no one was there .
Should I be worried that I haven't met the ?Should I ask him about it ?  
I'm really nervous about asking because he once told me he has never brought a girl gone before
