Hi! This phase can be quite a challenge in the life of any person in the world.
Just make sure you are not rude or anything to your parents. Just explain to them there is someone special to you-you would like them to meet. When they meet the person you say the person would like to date you.
Perhaps presenting a "friend" is better than a "boyfriend" firsthand.
It is important to consider their opinion as well, after all, parents have a lot of experience and can tell whether or not that person seems good to you. Of course, your opinion matters most, but it is always good to get a second opinion.
