well i think you should have a word with mom and dad to see what they have to say . cause what usually happens is they get scared and start thinking all this kind of thoughts . you know parents could be parents and depending on how old you are too it just makes it difficult.but you have to act mature and let them know that they can have trust for you and if they don't like your b/f they will have to learn how to like him just for you . that's just my opinion
