I was very shy but interested in sex as a pre-teen and a teenager. I learned to deal with that and became comfortable talking about sex (to the dismay of some people in my company, LOL!) by reading about sex--both for pleasure (like erotica or looking at sexy images) and for information (such as sexual health, techniques and how everything works). That really went a long way in me becoming comfortable with it, because it's a private way of examining sex, and masturbation helps, too, because you learn to be more comfortable with your body.

There's no rush, and you shouldn't force yourself to have sex when you're not ready or comforable. If your boyfriend cares, he'll understand that you just need to educate yourself (again, there's no timetable, whatever pace suits you), and find out what pleases you by yourself. That's the way we learn how to teach others how to please us. Men and women don't automatically know how to please a lover, even if they've had many, because everyone is different. So, if you know what touches please you, what movements get you going, you can show someone else, so they can do that for you.

Eventually, you have to try to let someone else in, to experiment with, but that person should be understanding and patient. If they're not, if they pressure you or rush you, then end it right there and find someone who is right for you.
