Asexual biromantic 17 year old boy. I'm sorry - I don't even know what that is.
In any event, if you want to meet someone, you need to join a club, go to church, do volunteer work, do something that brings you in contact with other people. That way you will be around people that will share a like interest so it will be a natural conversation starter.
Secondly, I'm not fond of labels. Be who you are naturally. You are just beginning to explore your sexuality. You have hopefully years ahead of you in your life's journey. Be safe - glove up each and every time - no excuses.
