My advice is to try exploring yourself before you worry too much about having an orgasm with your boyfriend. I think it will be easier for you to have your first one by yourself, because that way you can do exactly what feels good, without worrying about telling your boyfriend what you like and what you don't like.
You said before that masturbation does nothing for you...Are you really turned on when you try it? If you're not turned on, or if you're uncomfortable, it won't work. Get into a really good sexual fantasy to get yourself in the mood, and then try to find what you like. Again, don't focus on having an orgasm. Just focus on what feels good, and keep doing it. Try lots of clitoral stimulation. If you haven't already, you might even want to try a vibrator.
I hope this helps you. Good luck!
