Hey Deliliah233, I read your post about your concerns regarding your larger labia, and your concerns about the teen aged boyfriend and his reaction. The first thing you need to know (if you haven't figured it out already) is that he is 10x more self conscience about the size of his penis than you are about your labia. If he is a decent guy, then he won't make a big deal about it, it should only take a conversation with him to let him know your concern.
It's been a couple months since you posted this, so this may be a moot point, in that you may not be with him any more; however, it sounds like you need to get yourself past this issue for any future relationships. I promise you, most guys prefer larger inner labias...I know I do.
Best of luck
